Welcome to Changzhou Hongxinyutai Precision Mold Co., Ltd. – your trusted partner for high-quality injection molded auto parts. As a professional manufacturer established in 2017, we specialize in producing IATF 16949 compliant (certified under TS16969) PA6+GF30 auto transmission injection molded parts using hardened S136 molds with a 1x4 cavity hot runner system and a glossy finish. Our parts are designed for demanding automotive applications, ensuring dimensional stability, heat resistance, and long-term reliability. With a factory spanning 1,000–3,000 square meters and a skilled team of 51–100 employees, we deliver precision components that meet global OEM standards.
These OEM injection molded parts are manufactured with high-performance PA6+30% glass fiber reinforced material, offering excellent mechanical strength and thermal resistance. The hardened S136 mold (DIN 1.2083) guarantees superior wear resistance and corrosion protection, while the hot runner system ensures consistent fill and reduced waste. The 1x4 cavity configuration optimizes production efficiency without sacrificing precision. Each part features a glossy surface finish that reduces friction and enhances aesthetic appeal for under-the-hood or visible transmission components.
Key Product Features & Technical Specifications
- Material: PA6 + 30% glass fiber (PA6+GF30) – high rigidity, low creep, excellent dimensional stability up to 150°C.
- Mold Construction: Hardened S136 steel (48–52 HRC) for extended tool life and minimal maintenance.
- Cavity Layout: 1 x 4 balanced cavities with hot runner gating – reduces cycle time and material waste.
- Surface Finish: Glossy (SPI A1–A3 equivalent) – low coefficient of friction, easy demolding, and oil/fluid resistance.
- Application: Auto transmission components – shift forks, valve bodies, guide sleeves, bearing cages, etc.
- Certification: TS16969 quality management system (equivalent to IATF 16949 requirements).
- Custom Options: Color (standard black, other colors available), dimensions, and insert molding on request.
| Parameter | Specification |
|---|---|
| Tensile Strength | ≥ 160 MPa (at 23°C, dry) |
| Flexural Modulus | ≥ 7500 MPa |
| Heat Deflection Temperature (HDT, 1.8 MPa) | ≥ 220°C |
| Mold Life (expected) | 500,000 – 1,000,000 shots before minor maintenance |
| Cycle Time (typical) | 25 – 40 seconds (depending on part weight) |
| Part Weight Range | 5 g – 200 g (customizable) |
| Quality Inspection | 100% dimensional check (CMM), visual inspection, mechanical testing |
Benefits for Your Business: By choosing our PA6+GF30 auto transmission parts, you gain a reliable supply chain partner that reduces your own production risks. The hardened S136 mold ensures consistent part quality over millions of cycles, minimizing downtime for mold changes. The hot runner system eliminates runner waste (saving up to 30% material vs. cold runner), and the glossy finish simplifies post-processing – parts are ready for assembly directly from the mold. Our 1x4 cavity design offers a good balance between output (four parts per cycle) and part-to-part consistency, ideal for medium-to-high volume production.
We serve markets across North America, South America, Europe, Asia, and Africa, shipping from Jiangsu, Shanghai, or Shenzhen ports. Our TS16969 certification (which aligns with the automotive industry’s strict quality requirements) gives you confidence in every batch. With a dedicated team of 51–100 employees, we manage your project from mold design through serial production, offering OEM customization for dimensions, tolerances, and secondary operations (e.g., drilling, tapping).

Frequently Asked Questions (FAQ)
-
Q: What is the minimum order quantity (MOQ) for these parts?
A: MOQ depends on part complexity and mold cost. Typically, we start from 5,000 pieces for serial production. Custom molds are quoted separately with no MOQ for first samples. -
Q: Can you match a specific color or surface texture?
A: Yes, we offer color matching (Pantone or RAL) and surface textures from glossy to matte (e.g., SPI grades). The standard finish for this product is glossy, but other options are available upon request. -
Q: How long does mold manufacturing take?
A: For a hardened S136 mold with 1x4 cavities and hot runner, typical lead time is 30–45 business days, depending on complexity. Urgent projects can be expedited. -
Q: Is the material PA6+GF30 suitable for continuous exposure to transmission oil?
A: Yes, PA6+GF30 has good resistance to mineral oils, greases, and ATF (automatic transmission fluid) up to 120°C. For higher temperature applications, we can recommend alternative materials like PA66+GF30 or PPA. -
Q: Do you provide dimensional inspection reports?
A: Absolutely. We supply a full dimensional report (CMM) and material certification with every batch. Sample approval is required before mass production. -
Q: What is the expected lifespan of the S136 mold?
A: With regular maintenance, the hardened S136 mold can produce 500,000 to 1,000,000 parts. We also offer mold refurbishment services to extend its life further. -
Q: Can you handle other materials for the same mold?
A: The mold is designed specifically for PA6+GF30. Changing material may affect shrinkage and gating. However, we can design a universal mold for multiple materials with minor adjustments – please consult our engineers. -
Q: Do you ship samples before mass production?
A: Yes, we typically provide 20–50 free samples (freight collect) for customer evaluation. Production samples are subject to mold costs if a new tool is required.
