Automotive Door Handle Injection Molds

Tengrui Mould's Automotive Door Handle Injection Molds are customized for door handle forming, integrating advanced design and precision manufacturing. The integrated cavity and standardized mold base ensure molding stability and efficient mass production, flexibly adapting to different models' door handle shapes while balancing appearance precision, stability and durability. As a trusted supplier, we adhere to quality-first principles to deliver high-performance molds.

Core Selling Points

1.High-Precision Forming

The cavity undergoes CNC precision machining and mirror polishing, eliminating flow marks and flash on door handle surfaces. Strict control of dimensional accuracy and surface quality meets automotive exterior parts' harsh standards, ensuring consistent, exquisite appearance.

2.Efficient Production

Featuring dual-cavity design and optimized gating/cooling system, the mold shortens single injection cycle to under 45 seconds, greatly improving efficiency to meet automotive manufacturers' mass production needs.

3.High Durability

Core components are made of wear-resistant steel, reaching HRC52-56 after vacuum heat treatment. Service life exceeds 500,000 mold cycles under normal production, reducing replacement frequency and long-term costs.

4.Flexible Adaptability

Replacing inserts adapts the mold to different door handle shapes, avoiding new mold development for each project. This reduces development costs and shortens project cycles, supporting customized door handle development.

Material Selection

Tengrui Mould strictly controls material quality, selecting high-performance steels for each component to ensure the overall performance of our molds:

- Mold Base: S50C carbon structural steel, featuring excellent rigidity and machinability for stable long-term operation.

- Cavity and Core: 2344 or NAK80 mold steel, offering high hardness, wear resistance and superior mirror polishing performance.

- Guide Components: SUJ2 bearing steel guide pillars/bushings, ensuring precise and stable mold opening/closing without dimensional deviation.

- Auxiliary Accessories: SKD61 hot work mold steel for ejector pins/inserts, with excellent thermal deformation resistance for high-temperature injection cycles.

Manufacturing Process

1. Mold Design: 3D modeling-based simulation optimizes runners, cooling circuits and ejection systems, predicting potential issues via mold flow analysis to guarantee quality and efficiency.

2. Precision Machining: Five-axis CNC, EDM and wire cutting technologies control cavity dimensional accuracy within ±0.02mm, achieving micron-level precision.

3. Surface Treatment: Cavity mirror polishing (Ra ≤ 0.02μm); mold base blackening/nitriding enhances rust and wear resistance, extending service life.

4. Assembly and Debugging: Repeated test molding and parameter optimization ensure door handles meet customer requirements before delivery. Our factory in China strictly enforces this process for consistent quality.

Application Scenarios

These Automotive Door Handle Injection Molds are applied in automotive OEMs and component suppliers' production lines, suitable for mass-producing internal/external door handles for sedans, SUVs and new energy vehicles, as well as brand-customized projects.

Quality Assurance

- No less than 500 consecutive test molds before delivery, ensuring stable forming and zero quality defects.

- 12-month warranty, covering free repair/replacement for non-artificial damage to mold components.

- Professional after-sales team provides remote debugging, on-site maintenance and process optimization to ensure smooth production.
