Custom UHMW Injection Molding Product
If UHMW is right for your application, simply send us your drawings or samples. We’ll evaluate your design and deliver UHMW injection molded parts tailored to your requirements.
Custom UHMW Molding Solution
Zhongren provides custom UHMW injection molding solutions for industrial components that demand extreme wear resistance, low friction, and outstanding impact strength. Our expertise in UHMWPE molding allows us to manufacture parts with excellent chemical resistance and durability, ideal for high-load, high-abrasion environments. UHMW injection molding provides exceptional abrasion resistance and impact strength in tough environments where conventional plastics wear out, deform, or fail under stress.
How Are UHMW Parts Manufactured?
We utilize advanced molding techniques and equipment to shape UHMWPE into high-performance parts.
- UHMWPE CNC Machining
- Compression Molding with UHMW
Due to its high viscosity, UHMW injection molding requires specialized processing and precise tooling. Strict control of processing temperature, pressure, and cycle time is essential for consistent part quality.
Common Applications of UHMW Molding
Thanks to its exceptional wear and impact properties, UHMW injection molded parts are widely used in:
- Wear strips and guide rails
- Gears, bushings, and bearings
- Food processing and packaging components
- Medical and pharmaceutical parts
- Material handling systems
- Marine and agricultural equipment
Our Valued-Added Services
- Design and Engineering Support
- Material Testing and Certification
- Surface Finishing and Printing
- Assembly and Sub-Assembly
- Custom Packaging and Labeling
Advantages of UHMW Injection Molding
- Extremely high abrasion and wear resistance
- Low coefficient of friction (self-lubricating)
- High impact strength (even at low temperatures)
- Excellent chemical and moisture resistance
- Compliant grades available for FDA and USDA applications
Disadvantages of UHMW Molding
- Difficult to injection mold without specialized equipment
- Lower dimensional stability compared to other plastics
- Limited adhesion and bonding options
- Not suitable for applications above 80–90°C
- Limited colorability and surface detailing
FAQ of UHMW Injection Molding
How does UHMW compare to other plastics like nylon or PTFE?
UHMW has better impact resistance and lower friction than nylon, and superior abrasion resistance to PTFE. However, it has lower temperature resistance than both.
Can UHMWPE be overmolded or used in insert molding?
Yes, but bonding to UHMW is difficult due to its non-stick surface. Mechanical interlocks are often required for overmolding or inserts.
Are food-grade UHMW materials available?
Yes, we offer FDA and USDA-compliant UHMW injection molding solutions suitable for food contact and hygiene-sensitive applications.
What’s the lead time for custom UHMW molding projects?
Lead times vary depending on tooling complexity, but typical turnaround for new tooling is 3–5 weeks. Production can begin once tool validation is complete.
