Custom Plastic Components for Industrial Applications
We manufacture made-to-order plastic components for customers in industrial equipment, automation, electronics, automotive, machinery, chemical processing, and other industries.
Unlike standard off-the-shelf plastic products, each part can be manufactured according to the customer's specific drawing and application requirements.
Our custom plastic manufacturing capabilities include:
- CNC machined plastic parts
- Injection molded plastic parts
- Plastic gears and rollers
- Plastic bushings and sleeves
- Plastic blocks and plates
- Plastic housings and covers
- Plastic brackets and structural components
- Insulating plastic components
- Wear-resistant plastic parts
- ESD and antistatic plastic parts
Custom prototypes
Replacement parts for industrial equipment
Whether you need a single prototype, a small production batch, or repeat production, we can evaluate the most suitable manufacturing process based on your design, material, quantity, tolerance, and target cost.
Materials Available
We work with a wide range of engineering plastics, including:
- POM / Acetal
High dimensional stability, low friction and good wear resistance. Commonly used for gears, bushings, rollers and precision mechanical components.
- PA / Nylon
Good mechanical strength and wear resistance, suitable for industrial mechanical parts and structural components.
- PEEK
High-performance engineering plastic with excellent heat resistance, chemical resistance and mechanical properties.
- PTFE / Teflon
Excellent chemical resistance and low friction, commonly used for seals, guides, insulators and chemical equipment components.
- UHMW-PE
Excellent wear resistance and low friction, suitable for guides, wear strips, rollers and material handling equipment.
- PC / Polycarbonate
High impact strength and good dimensional stability, suitable for covers, housings and structural components.
- ABS
Cost-effective and easy to process, widely used for housings, prototypes and general-purpose plastic components.
- PP / PE / PVC
Available for various industrial, chemical and general-purpose applications.
We can also evaluate ESD, antistatic, conductive, glass-fiber reinforced, carbon-fiber reinforced and other modified engineering plastics according to your application.

Custom Manufacturing Capabilities
Depending on the part design and required quantity, we can provide different manufacturing solutions.
- CNC Machining
Suitable for precision parts, prototypes, low-volume production and projects that do not justify mold investment.
- Injection Molding
Suitable for medium- to high-volume production where stable repeatability and lower unit cost are required.
- Prototype & Small Batch Production
Ideal for product development, testing, replacement parts and initial production runs.
We can manufacture parts according to:
- 2D drawings
- PDF drawings
- STEP / STP files
- CAD models
- Physical samples
- Customer specifications
