What sets a excellent mold supplier apart is their ability to actively coordinate, communicate effectively, and accurately resolve issues.
Dustproof workshop: independent dust-proof assembly area.
Temperature and humidity control: temperature 22 ± 3 ℃, humidity<60%.
Anti static: equipped with anti-static workstations, grounding wristbands, and anti-static work clothes (available as needed).
Fixtures: Quick changing manual/pneumatic clamping fixtures that can quickly produce simple fixtures for different products.
This section shows the four core processes of mold production, including detailed parameters and standards for each process to ensure product quality and production efficiency.
| Process Name | Key Content Points |
|---|---|
| Deburring and trimming | Remove excess burrs generated by the mold parting line or top pin position |
| annealing | Eliminate internal stress in injection molding to prevent subsequent deformation or cracking |
| Moisture control treatment | Balance control stabilizes dimensions and optimizes the performance of nylon components |
| Process Category | Key process | Key Content Points |
|---|---|---|
| Spraying | Spray painting (such as UV paint/PU paint) | Enhanced adhesion, weather resistance, and automatic Pantone or RAL color matching available |
| Electroplating | Water plating/vacuum plating | Decorative metal texture, corrosion-resistant and wear-resistant |
| Screen printing/transfer printing/thunder carving | High precision marking | 2D to 3D transfer printing, anti-counterfeiting precision labeling |
| Gold stamping | Heat transfer metal decoration | Luxury surface decoration effect |
| Process Category | Key process | Key Content Points |
|---|---|---|
| Mechanical locking | Use a preset torque screwdriver to tighten the screws | Torque values can be recorded by batch |
| Adhesive bonding and dispensing | Manual dispensing or semi-automatic dispensing machine (milligram level accuracy) | UV curing, fast drying adhesive, two-component epoxy with milligram level quantitative accuracy; Support multiple adhesive types (UV/instant dry adhesive/two-component epoxy) |
| Welding and Connection | Hand soldering iron (wire harness/PCB)、Hot air gun welding、Optional small pulse hot pressing welding | Covering wiring harnesses, PCB boards, flexible circuit boards, etc; Provide pulse hot pressing precision welding options |
| Press fit and riveting | Small manual or pneumatic press bed | Suitable for interference fit parts such as bearings, pins, and shaft sleeves |
| Hot burial | Metal nuts/thread forming | Enhance the subsequent machine locking force of plastic parts |
| Component assembly | Labels, buckle fit, etc | Enhance the completeness of BOM supply |
| Process Category | Key process | Key Content Points |
|---|---|---|
| Full Inspection Report (FAI) sent for testing | Optical imaging instrument/CMM | Provide documents for key dimensions |
| Cleaning packaging | Oil removal, electrostatic precipitator, vacuum bag | Automotive medical requirements for dust-free transportation |
| Air tightness/liquid tightness test | Use a simple airtighter or negative pressure attenuation tool | Perform leakage testing on the shell, pipeline, and joints |
In order to ensure that the quality of every product leaving the factory meets the requirements, we have established strict quality control measures.
Incoming inspection: Conduct size/appearance sampling or full inspection on each batch of parts, and reject any non-conforming items.
First piece confirmation: The first piece of each batch is confirmed for size, assembly effect, and function by the quality inspector, and signed for release.
Process inspection: Every 30-60 minutes or every 50 pieces, check key parameters (torque, dispensing amount, pressing force).
Complete inspection: Small batches can be 100% manually inspected. If any defects are found, they will be repaired or removed, and recorded and archived.
Traceability: Paper or simple electronic batch records (operator, date, inspection results).
