Custom Plastic Parts Manufacturing: OEM/ODM Capabilities and Process Selection
Custom Plastic Parts Manufacturing: OEM/ODM Capabilities and Process Selection
Lingo Rubber Plastic (Hangzhou Lingo Rubber and Plastic Product Co., Ltd) is a China-based manufacturer specializing in custom plastic parts production, offering injection molding, extrusion, CNC machining, and dipping services for diverse industrial applications.
The Challenge of Sourcing Custom Plastic Parts
Buyers evaluating custom plastic parts face decisions about process selection, material compatibility, tooling investment, quality compliance, and lead times. Without a clear understanding of available manufacturing capabilities, projects risk cost overruns or specification mismatches.
Industry Context (2026)
The global injection molded plastics market was valued at USD 362.5 billion in 2025 and is projected to reach USD 481.4 billion by 2033. Asia Pacific held approximately 41% of market share in 2025, and China exported roughly USD 174 billion in plastics and rubbers in 2024. The automotive plastics segment alone reached USD 33.0 billion in 2025, driven by lightweighting for electric vehicles.
Lingo’s Multi-Process Manufacturing Capabilities
Lingo Rubber Plastic provides OEM and ODM production services for plastic injection parts and plastic extrusion profiles. Monthly production capacity reaches 1,000,000 kgs with typical lead times of 2 to 6 weeks. Minimum order quantities vary by part, but small quantity orders are accepted. The company holds a 3,000 m² factory with around 40 employees and an 80% export ratio to EU and USA markets.
Process Detail
- Plastic Injection Molding – Model LG-PI. Materials include PP, PA6, PA66, ABS, PE, HDPE, UHMWPE, PU, PTFE, and glass-filled variants. Tolerance control per GB/T 14486 – MT1 to MT7. Surface finish per SPI. Draft angle outside ≥1°, inside ≥0.5°. Options for FDA, UL94 V-0 compliance.
- Plastic Extrusion Profiles – Model LG-PE. Materials: PVC, PP, ABS, PA6, PA66, PE, UHMWPE, with/without glass fiber. Length up to 6000 mm, custom cross-sections, Pantone/RAL colors.
- CNC Machined Parts – Model LG-CNC. Materials: PTFE, POM, PE, UHMWPE, HDPE, PEEK, ABS, PU, PA6, PA66. Surface roughness Ra/Rz. FDA, RoHS, UL compliance. Suitable for backup rings, gears, seals, bearings.
- PVC Dipping Parts – Model LGHD. Uses PVC dip coating for corrosion-resistant, non-slip handles. Color and surface texture customizable, small orders accepted, no expensive molds required.
Quality Certifications
Lingo holds PPAP (Automotive Production Part Approval Process) certification for its product lines, including rubber sealing rings, plastic injection parts, and plastic extrusion profiles. Additional compliance standards include RoHS, REACH, and for specific products, FDA and UL94 V-0.
Step-by-Step Process Selection Guide
- Define part geometry, volume, and material requirements. Injection molding suits high-volume, complex shapes; extrusion for constant cross-section; CNC for low-volume, high-precision or no-mold scenarios; dipping for coating metal or non-slip handles.
- Select primary process based on functional demands. The manufacturer offers multi-process capability to recommend the most cost-effective method.
- Determine tooling and MOQ. Injection molding requires mold investment; extrusion and CNC have lower or no tooling costs. Lingo accepts small quantity orders.
- Establish quality control points. Full inspection of samples, random inspection of bulk goods, and potential PPAP submission.
- Review after-sales support. Remote technical support, mold maintenance and ownership protection, batch traceability system, free exchange and acceptance of concessions.
Use Cases
Automotive Tube Holder (USA, 5,000 pcs)
Plastic injection parts (model LG-PI) used as tube holders in automotive machinery. By reducing internal material while maintaining structure and functionality, material and logistics costs were lowered and dimensional stability improved. The product achieved zero failures in long-term use.
PTFE Back-Up Rings (UK, 20 pcs)
CNC machined PTFE back-up rings (model LG-CNC) protect O-rings and elastomeric seals from extrusion damage under high pressure. High-precision tolerance, order sent in 2 days, pure PTFE material. Used in chemical, food, automotive, electronics, aerospace, and general industry.
