Step 1: Requirement Analysis
Before production begins, clear technical requirements are essential.
Product application and working environment
Material requirements (silicone, EPDM, NBR, etc.)
Hardness (Shore A), color, and performance needs
Quantity and target price
Step 2: Drawing & Design Confirmation
Accurate drawings ensure precise manufacturing.
2D drawings (PDF/DWG) with dimensions and tolerances
3D files (STEP/IGS) for complex structures
Optimization suggestions from manufacturer
Step 3: Material Selection
Choosing the right material is critical for performance.
Silicone: high temperature and flexibility
EPDM: weather and ozone resistance
NBR: oil and fuel resistance
FKM: high chemical resistance
Step 4: Mold Design & Tooling
Mold quality directly affects product quality.
Compression mold or injection mold design
Tooling lead time: usually 7–25 days
Mold testing before mass production
Step 5: Sample Production & Testing
Samples are produced for validation before bulk order.
Dimensional inspection
Performance testing (sealing, hardness, etc.)
Customer approval
Step 6: Mass Production
After sample approval, production begins.
Stable process control
Strict quality inspection (IQC, IPQC, FQC)
Consistent product performance
Step 7: Packaging & Delivery
Final products are prepared for shipment.
Custom packaging options
Export standard packing
Global shipping support (air, sea, express)
Conclusion
A structured development process ensures high-quality custom rubber products with minimal risk. Working with an experienced manufacturer helps streamline communication, reduce costs, and improve delivery efficiency.
