Door Lock Plastic Parts

Premium Door Lock Plastic Parts Manufacturer | Custom Injection Molding Solutions

We specialize in metal and plastic injection molding, delivering end-to-end manufacturing solutions from product design review and mold development to material selection, precision injection molding, and final assembly.

Core Door Lock Plastic Components

• Door Lock Plastic Parts: ±0.02mm tolerance strikers, latches, and cam mechanisms.
• Plastic Rotary Dampers: 2−20N⋅m torque range for smooth door closing.
• Clip-In Plastic Magnet Latches: 0.5−5kg magnetic holding force.
• Plastic Strikers: UL94 V-0 flame rated, wear-resistant formulations.
• Plastic Push Latches: Customizable activation force (3−8N)

Select engineering plastics based on functional requirements:

• ABS: 60−80°C operating temp, ideal for indoor hardware.
• PC/ABS: High impact strength (>500J/m notched Izod).
• PA (Nylon): Excellent wear resistance (<0.1 friction coefficient).
• POM: Low moisture absorption (<0.25) for dimensional stability.
• TPE: Soft-touch components with >300 elongation.

Precision Manufacturing

• 88-650 ton injection molding machines
• SPC-controlled process parameters:
  Injection pressure: 800−2000bar
  Mold temp control: ±1°C accuracy
  Cycle time optimization: 15−90s depending on part geometry

• Secondary Processing: Drilling (±0.05mm), tapping, ultrasonic welding.
• Surface Treatments: Texture polishing, silk printing, vacuum metallization.
• Quality Assurance: Full PPAP documentation, 100 batch testing
