Yes. For customers developing new membrane products or upgrading existing processes, Trustech can participate beyond the role of a conventional equipment supplier and provide joint technical development and scale-up support.

The cooperation can begin with the membrane's target specifications, material system, fiber structure, production capacity, and application requirements. Based on these inputs, Trustech's engineers can work with the customer on:

• Spinneret development – Optimize hole geometry, flow channels, and multi-bore structures according to the target membrane design.
• Process and equipment matching – Evaluate the relationship between the membrane formulation, spinning conditions, spinneret, and production-line configuration.
• Pilot testing and commissioning – Support process trials and equipment adjustment before moving toward larger-scale production.
• Scale-up support – Help translate laboratory or pilot results into a more stable industrial production process.
• Continuous optimization – Use production feedback and test results to identify opportunities for improving stability, efficiency, and membrane consistency.

This collaborative approach is particularly valuable when the customer is working with new membrane materials, specialized hollow fiber structures, medical membranes, gas-separation membranes, or other applications where the process window is relatively narrow.

Rather than asking customers to finalize every technical parameter before purchasing equipment, Trustech can work with them to gradually define the relationship between membrane design → spinneret → spinning process → equipment → production performance.

For customers with long-term R&D plans, this provides a practical path from laboratory concept to pilot validation and eventually industrial-scale production.

Yes. Trustech can provide technical documentation and training materials required for equipment installation, operation, maintenance, and project acceptance, subject to the specific project and documentation requirements.

Depending on the equipment or spinneret supplied, documentation may include:

• Technical specifications and configuration information
• Installation drawings and relevant engineering documents
• Spinneret inspection or dimensional reports
• Equipment operation and maintenance manuals
• Process and commissioning references where applicable
• Inspection and acceptance records
• Technical training for installation, operation, maintenance, and troubleshooting

For equipment projects, Trustech can provide technical guidance during commissioning and help the customer's engineering team understand key operating and maintenance requirements. Training can be conducted remotely or on site depending on project needs.

These documents also provide a useful technical basis for customers conducting internal supplier reviews, equipment acceptance, production qualification, or external certification activities.

Because documentation requirements vary between industries and projects, customers are encouraged to communicate their audit or certification requirements during the quotation stage so that the required documentation can be confirmed in advance.

Trustech provides technical support throughout the operation of its spinnerets and membrane production equipment. When a problem occurs, the first step is to identify the cause rather than simply replace a component.

After receiving customer feedback, Trustech normally provides an initial response within 24 hours. Engineers can review operating conditions, process parameters, equipment status, and relevant photos or videos to conduct remote diagnosis. For more complex issues, on-site technical support can be arranged when necessary.

Troubleshooting generally follows a structured approach:

• Collect information – Review the membrane specification, process parameters, equipment status, operating conditions, and abnormality records.
• Identify the root cause – Determine whether the issue may be related to process conditions, equipment, materials, operation, or other factors.
• Provide corrective measures – Recommend immediate countermeasures to restore stable operation where possible.
• Follow up on the result – Verify whether the recommended adjustment resolves the problem and determine whether further improvement is required.

Trustech also provides technical resources through its online FAQ and video tutorial sections to help customers handle common operating and maintenance questions.

If an issue is ultimately determined to be attributable to Trustech's design or manufacturing responsibility, the corresponding remedial action, such as repair, rework, or replacement, will be handled according to the agreed commercial and technical terms.

The objective is not simply to solve one incident, but to identify its root cause and use the experience to improve future operation and product reliability.

Trustech manages quality through a combination of ISO 9001 quality management, process control, precision inspection, and product traceability.

Quality control begins with incoming materials and continues throughout machining, assembly, inspection, and final delivery. Key manufacturing processes are monitored to ensure that critical dimensions and performance requirements remain within the specified range before products are released.

For spinnerets, particular attention is given to precision parameters such as micro-hole dimensions, concentricity, and eccentricity, supported by dedicated microscopic and image-based inspection methods. Equipment is also inspected and tested according to its configuration and project requirements.

Traceability is an important part of this system. Production and inspection information is recorded throughout the manufacturing process, allowing relevant product or batch information to be reviewed when necessary.

For customers, this means that quality is not based solely on final inspection. It is supported by a controlled manufacturing process that makes potential deviations easier to identify, analyze, and correct.

Different membrane applications place different demands on fiber geometry, flow distribution, material compatibility, process stability, and production efficiency. Trustech therefore does not apply one standard spinneret or spinning configuration to every application.

For water purification and liquid separation, including MF, UF, NF, MBR, and desalination, the focus is generally on stable continuous production, suitable flux, consistent fiber geometry, and scalable output. Trustech provides spinnerets with concentricity of around 0.003 mm for separation-membrane applications, together with NIPS/TIPS spinning solutions for different production requirements.

For hemodialysis and other medical membranes, tighter control of surface quality, dimensional accuracy, eccentricity, and fiber consistency becomes particularly important. Trustech's application portfolio includes dedicated spinnerets for hemodialysis and artificial-kidney membranes, with reported eccentricity reaching approximately 0.003 mm.

For gas separation and artificial-lung applications, spinneret design needs to support precise and consistent formation of specialized hollow fibers. Trustech provides polymer-fiber spinning spinnerets for gas-separation applications, with reported concentricity reaching approximately 0.0003 mm for relevant products.

For RO flat-sheet membrane production, the focus shifts from hollow-fiber geometry to coating and casting consistency. Trustech's flat-sheet systems are designed around continuous casting/coating processes and can integrate systems for heating, mixing, web handling, winding, and process control.

The key advantage is that customers can evaluate the membrane material, structure, process route, production capacity, and equipment configuration together, rather than selecting a spinneret or machine in isolation.

Trustech has developed dedicated micro-deep-hole manufacturing and precision machining capabilities for polymer fiber spinnerets. Its manufacturing processes can achieve step-diameter concentricity of approximately 0.002 mm, with hole concentricity reaching around 0.005 mm under the corresponding process conditions. Automated processing and precision fixtures are also used to maintain consistency between different machining operations.

Inspection is equally important. Trustech combines microscopic and image-based inspection with its Microtech Image Test software to evaluate critical parameters such as micro-hole dimensions, concentricity, and eccentricity.

For customers, the value is not simply achieving high precision on one prototype. The combination of precision machining + dedicated inspection + process control helps establish a repeatable manufacturing process for subsequent batches.

This is particularly important for applications such as hemodialysis, gas separation, and high-performance water-treatment membranes, where consistency between holes and between production batches can directly affect membrane performance.

If you have a required hole diameter, concentricity, or multi-bore structure, send us your specifications and we can evaluate the appropriate manufacturing approach.

For a technical equipment supplier, qualifications and industry recognition are more than certificates on the wall. They provide customers with an additional reference for evaluating a supplier's technical capability, quality management, industry experience, and long-term reliability.

Trustech is recognized as a National High-Tech Enterprise and a China Technology-Based SME, and is a member of the China Membrane Industry Association. The company also holds an AAA credit rating and has obtained more than 40 authorized patents and other intellectual property rights related to membrane spinning and spinneret technologies.

Trustech also participated in the development of the group standard “Hollow Fiber Membrane Spinneret” (T/SHDSGY 058-2022). In addition, its technologies have been recognized as being at a domestic leading level through technology appraisal/search activities.

For customers, these qualifications provide useful evidence that Trustech is not simply a trading company supplying standard components, but an R&D-driven manufacturer with established capabilities in precision manufacturing, membrane spinning technology, and continuous product development.

When evaluating suppliers for a long-term membrane production project, customers can therefore consider not only the quotation, but also the supplier's technical credentials, quality system, intellectual property, industry participation, and track record.

MEMTOOLS is an online engineering reference tool developed by Trustech to help membrane R&D and production teams with capacity planning, process calculations, and preliminary spinneret selection. It digitalizes part of Trustech's accumulated experience in membrane spinning and equipment engineering.

The tool focuses on four practical functions:

• Capacity Estimation
  Engineers can enter parameters such as fiber dimensions, number of spinneret holes, spinning speed, working shifts, or flat-sheet dimensions to estimate daily, monthly, and annual production capacity.
• Reverse Configuration
  Starting from a target production capacity, engineers can work backward to estimate key configuration requirements such as spinneret hole numbers, pump specifications, and reactor volume.
• Process Tuning Reference
  The tool provides reference calculations for dope and bore-liquid consumption, helping engineers evaluate flow-rate requirements and identify potential process-balance issues during spinning.
• Spinneret Specification Reference
  MEMTOOLS includes 210+ specification references covering different spinneret types and membrane processes, supporting preliminary comparison during R&D and equipment planning.

For engineers, the value is not simply faster calculation. MEMTOOLS helps turn preliminary production targets and process parameters into more structured engineering references, reducing repetitive calculations and supporting faster equipment and spinneret evaluation.

The tool is intended as an engineering reference rather than a substitute for project-specific validation. Final process parameters and equipment configurations should always be confirmed against the customer's actual materials, membrane design, and production conditions.

High-performance membrane applications require much tighter control of fiber geometry, wall thickness, pore structure, material flow, and process stability than many conventional membrane applications. This is why Trustech has focused its R&D on precision spinnerets and coordinated spinning systems.

Trustech's advantages include:

• Precision spinneret technology: Hollow fiber spinnerets directly influence key membrane characteristics such as concentricity, wall-thickness uniformity, pore-size distribution, and overall separation performance. Trustech's current manufacturing capability can reach machining precision of approximately 0.002 mm.
• Experience across demanding membrane applications: Trustech's products are used in areas including hemodialysis, gas separation, water purification, MBR, ECMO, and chemical processing, giving its engineering team experience across different membrane structures and process requirements.
• Integrated equipment capability: Trustech develops not only spinnerets but also NIPS/TIPS hollow fiber spinning machines and flat-sheet membrane casting systems, allowing spinneret design and process equipment to be considered together rather than independently.
• Continuous R&D: The FCT platform has developed through multiple generations, supported by more than 40 patents and other intellectual property rights, reflecting continued investment in spinneret and spinning-system technology.

This combination makes Trustech more than a component supplier. For customers developing or industrializing high-end membranes, Trustech can contribute to the transition from membrane concept → spinneret design → pilot spinning → process optimization → production-scale equipment.

Trustech approaches membrane spinning as an integrated system rather than treating the spinneret as an isolated component. Its NIPS, TIPS, and flat-sheet membrane systems combine process engineering with improvements in heating, mixing, feeding, winding, and drive control to improve consistency and reduce production interruptions.

Key system technologies include:

• SteadyiCore Ultra 2.0 Heating System: Provides a more uniform thermal profile, with temperature control reported at approximately ±1°C, helping reduce fluctuations in dope and process conditions.
• TitanMix Pro 4.0 Mixing System: Improves mixing uniformity and can shorten mixing time by 20–50%, helping reduce batch-to-batch variation.
• PrimeGlider Pro 3.0 Automatic Pay-off: Provides smoother and more stable filament handling, reducing dependence on manual adjustment.
• SmartCoil Elite 3.0 Automatic Winding: Automates winding with more precise control, helping reduce labor requirements and improve winding consistency.
• StoutDrive 2.0 Drive System: Supports stable and accurate line-speed control during spinning.
• Process Monitoring & Automation: Key parameters such as flow, pressure, and temperature can be monitored to provide a stronger data basis for process optimization.

According to Trustech, these system-level improvements have contributed to an overall 11.4% increase in spinning efficiency compared with pre-improvement performance, while also reducing commissioning and production downtime.

The practical benefit is a more coordinated production system: stable temperature + uniform mixing + controlled material delivery + stable take-up = more consistent membrane production and less manual intervention.

Trustech's FCT (Fast Change Technology) spinnerets have evolved from conventional fixed structures toward higher precision, modularity, easier maintenance, and greater production continuity. The FCT technology was introduced in 2016 with the 5th generation, followed by continuous development of later generations. Trustech's current technology portfolio highlights independent spinneret cores, pinless structures, and rapid core replacement, with machining precision reaching 0.002 mm.

The key developments include:

• 5th Generation – Independent Core Design: The split, modular spinneret-core structure allows individual cores to be removed and replaced, reducing the risk of damaging the entire spinneret during maintenance. It is used for applications including water treatment, MBR, gas separation, and hemodialysis membranes.
• 6th Generation – Independent Flow Control: Each spinneret core can be controlled independently for dope feeding. This allows operators to isolate or adjust individual positions when abnormalities occur, rather than affecting the entire spinneret.
• 7th Generation – Pinless & Screwless Structure: The simplified modular architecture makes assembly, disassembly, cleaning, and maintenance more convenient while reducing structural complexity.
• 8th Generation – Rapid Online Core Replacement: Individual spinneret cores can be replaced while the production system remains in operation. Depending on the configuration, replacement can be completed within minutes and, in some applications, in as little as around 50 seconds, helping minimize production interruption.
• Later-Generation Multi-Orifice Development: Trustech continues to develop modular multi-orifice structures and optimized flow-channel designs to support higher-throughput and multi-bore membrane production.

For membrane manufacturers, these innovations mean more than a new spinneret structure: they translate into less maintenance downtime, lower replacement costs, more stable spinning, and greater flexibility in production planning.

Lead time depends mainly on the product type, customization level, and project configuration.

As a general reference:

• Standard or slightly modified hollow fiber membrane spinnerets: approximately 15–25 days.
• Custom spinnerets, such as special geometries, multi-bore structures, or special materials: approximately 25–40 days, depending on complexity.
• NIPS/TIPS hollow fiber spinning lines and complete RO flat-sheet coating systems: typically 2–5 months, including engineering, manufacturing, assembly, and in-house testing.

For urgent projects, Trustech can evaluate the possibility of priority scheduling, advance material preparation, and adjusted production arrangements. The actual expedited schedule depends on the product structure, engineering workload, material availability, and current production capacity.

For projects with strict deadlines, it is recommended to communicate the required delivery date at the quotation stage so that the project team can evaluate the most practical production schedule in advance.

Tell us your required delivery date and project configuration, and Trustech can assess the available schedule for you.
