Key Features & Benefits
- High Strength & Heat Resistance: PA6+GF30 offers excellent tensile strength and thermal stability, ideal for transmission parts operating under high temperatures and mechanical loads.
- Precision Mold Steel: S136 stainless mold steel provides superior corrosion resistance, wear resistance, and mirror-polished cavity surfaces, ensuring consistent part quality over long production runs.
- 1x4 Cavity Efficiency: Four cavities per shot increase productivity without compromising part quality, reducing per-unit cost.
- Hot Runner System: Eliminates cold runner waste, reduces cycle time, and improves temperature control for consistent filling.
- Robotic Arm Integration: Fully automated part removal minimizes human error, shortens cycle time, and allows for unmanned operation during breaks.
- Customizable Design: We tailor mold design and part specifications to your exact dimension, tolerance, and performance requirements.
- Fast Sampling & Lead Time: Our experienced team (51–100 employees) and dedicated project management ensure T0 samples within 25–35 days, with mass production shipping within 4–6 weeks.

Frequently Asked Questions (FAQ)
-
Q: What is the minimum order quantity (MOQ) for custom injection molded transmission parts?
A: MOQ depends on part size and complexity. Typically, we accept orders from 1,000 to 5,000 pieces for initial tooling trials, but we can discuss lower quantities for prototype molds. Contact us for a tailored quote. -
Q: Can you produce parts with different colors or surface textures?
A: Yes. We can add pigments to PA6+GF30 during molding, and surface finishes such as gloss, matte, or textured (VDI, SPI) are available upon request. -
Q: How long does the mold manufacturing take?
A: For a 1x4 cavity S136 hot runner mold, typical lead time is 25–35 working days from design approval to T1 samples. Rush orders may be possible with additional charges. -
Q: Do you provide any warranty on the mold and parts?
A: Yes, we offer a 12-month warranty on the mold (excluding consumables) and full support for part quality during mass production. Any defects due to tooling or process are covered. -
Q: Can you handle complex geometries like undercuts or internal threads?
A: Absolutely. Our mold design team can incorporate lifters, sliders, or hydraulic cores to produce undercuts and threaded features. Hot runner system with valve gates also helps control flow for complex shapes. -
Q: What is the advantage of using a robotic arm compared to manual pick-up?
A: Robotic arm ensures consistent cycle time, reduces operator risk, and allows the mold to run in a fully automated “lights-out” mode, increasing overall equipment efficiency (OEE). -
Q: Do you have any experience with PA6+GF30 materials specifically for transmission parts?
A: Yes. We have produced numerous auto transmission components (e.g., shift levers, oil pump gears, valve spools) using PA6+GF30, achieving tight tolerances of ±0.05mm and excellent wear resistance. -
Q: Can you provide PPAP documents?
A: Yes, we can supply PPAP Level 3 documents including dimensional reports, material certifications, and process capability studies (CPk) upon request.
