PP Engineering Plastics Injection Molded Parts for Industrial Equipment
Our PP and engineering plastic injection molded parts are built to withstand the demands of industrial equipment manufacturing—continuous vibration, dust exposure, repeated assembly, and thermal stress. Leveraging our expertise in automotive-grade molding, we transfer that precision to industrial components such as protective covers, structural supports, and modular assemblies. With a 2,500 m² factory and 80 employees, we deliver robust parts that maintain dimensional stability and mechanical integrity over thousands of operational cycles.
Key Selling Points
- Wear-Resistant PP & Engineering Plastics: Materials selected for abrasion resistance and long-term stability under cyclic loading; PP offers excellent chemical resistance, while engineering grades (e.g., POM, PA) provide higher strength.
- Dimensional Stability: Parts maintain precise dimensions despite temperature fluctuations (-20°C to +80°C) and mechanical stress, ensuring consistent assembly over time.
- Robust Structure: Designed with adequate ribbing and wall thickness to withstand repeated assembly/disassembly during maintenance without cracking or deformation.
- Versatile Applications: Suitable for protective housings, machine guards, cable management components, and structural brackets in dusty workshop environments.
- Flexible Production: Support low-volume to high-volume runs with rapid mold changes; MOQ negotiable based on part complexity and material.

Models and Options
Customizable features:
- Choice of PP homopolymer, copolymer, or talc-filled grades for stiffness
- Optional metal inserts for threaded inserts or bearing mounts
- Additives: UV stabilizers, anti-static, flame retardant (UL94 HB rated)
Materials and Structure
Materials: PP (polypropylene) provides excellent chemical resistance and fatigue endurance. For higher mechanical loads, we offer engineering plastics like POM (acetal) for low friction and wear, or PA66 (nylon) for high strength. All materials comply with RoHS requirements.
Structure: Parts are designed with uniform wall sections to minimize warpage. Gussets and ribs add rigidity without excessive weight. For parts requiring repeated assembly, we incorporate durable snap-fit geometries or metal-threaded inserts.
Applications
- Protective covers for conveyor systems
- Machine guarding panels
- Equipment housing components
- Cable guides and wire management clips
- Structural brackets and support arms
Customization
We offer end-to-end customization:
- DFM analysis to optimize part design for tooling and manufacturing
- Prototype validation (3D printed or rapid tooled samples)
- Material selection assistance based on load, temperature, and chemical exposure
- Secondary operations: ultrasonic welding, pad printing, assembly of metal inserts
Case Study
Client: Industrial equipment manufacturer for packaging machinery
Application: Injection molded protective cover for a high-speed carton erector
Challenge: Required a low-cost, impact-resistant cover that could withstand occasional bumping from operators and exposure to dust and lubricants.
Solution: DTG recommended PP copolymer with UV stabilizer. Designed a 3-mm wall thickness with reinforced ribs and snap-fit assembly to eliminate fasteners.
Result: 5,000 units produced with consistent quality. Cover passed drop test (1m height) and showed no cracking after 100,000 cycles of assembly/disassembly testing.
FAQ
Can you produce parts in small quantities for prototype testing?
Yes. We offer low-volume prototyping using prototype tooling or 3D printing (for fit checks). Production tooling can follow after design validation.
What is the lead time for a new mold?
Typical lead time is 25–35 days for a steel mold, depending on complexity. We can expedite using aluminum tooling for shorter runs.
Do you provide material certificates?
Yes. We provide material test reports (MTR) and RoHS compliance certificates upon request.
Can you incorporate metal inserts during molding?
Yes. We use automated insert loading systems to place brass or stainless steel inserts during the molding cycle for secure retention.
How do you handle quality for industrial parts?
We perform 100% visual inspection and dimensional checks on critical features. First article inspection (FAI) includes CMM measurement and fit tests.
What shipping methods do you offer?
We ship via sea freight (FOB/CIF) or air freight (EXW). Samples can be sent via international courier (DHL, FedEx).
Can you match a specific color?
Yes. We can match any color using masterbatch pigments. For PP, we offer a range of standard colors as well.
Is your factory audited by third parties?
Yes. We passed the Made-in-China On-site Audit by Bureau Veritas (certificate number MIC-ASI217106).
