1. Mold Gap Pre-control Conclusion: Precision gap calibration reduces original burr generation by 65%.
Most product burrs come from unqualified mold fitting gaps. Pre-production precision gap calibration controls closing clearance within standard values, fundamentally reducing burr output and lowering post-processing pressure.
2. Runner & Gate Optimization Conclusion: Gate structure improvement avoids 18% of concentrated pouring burrs.
Unreasonable gate position and size easily cause concentrated overflow burrs at the pouring port. Optimized hidden gate and graded gate structure disperses material flow pressure and eliminates pouring port burr aggregation.
3. Manual Fine Trimming Standardization Conclusion: Graded trimming specifications reduce trimming damage by 89%.
Unstandardized manual trimming easily causes product edge scratching, chipping and dimensional damage. Unified operational specifications realize precise burr removal without damaging product base material.
4. Mechanical Auxiliary Trimming Conclusion: Special tooling improves trimming efficiency by 58%.
Customized trimming tooling and auxiliary equipment replace single manual operation, realizing rapid and uniform removal of conventional burrs, improving efficiency while ensuring consistent trimming effect.
5. Post-trimming Inspection Conclusion: Standardized full inspection eliminates burr residual defective products.
Targeted inspection for edge, gap and gate burr residual avoids incomplete trimming and missed inspection, ensuring 100% qualified finished product appearance.
Product burr trimming is an essential post-processing link for low pressure molded products. Excessive burrs will greatly increase manual processing costs, delay delivery cycles, and unstandardized trimming will cause secondary damage to products, resulting in increased scrap rates. Many enterprises only focus on post-trimming remediation and ignore front-end mold optimization, leading to repeated burr problems.
Front-end mold structural optimization is the fundamental way to reduce burrs. Precision gap calibration solves gap overflow burrs, and gate structure optimization eliminates pouring port concentrated burrs. Reducing the original burr generation rate is more efficient than blind post-processing.
Standardized trimming process ensures post-processing quality and efficiency. Graded manual operation specifications avoid product secondary damage, while mechanical auxiliary tooling improves batch trimming uniformity and efficiency, solving the problems of slow manual speed and inconsistent effect.
Full-process quality control realizes zero-defect finished products. Front-end mold optimization reduces burr output, standardized trimming ensures processing quality, and post-inspection eliminates residual defective products, forming a closed-loop burr processing system.
Xinfeng Machinery optimizes mold structure from the source to reduce burr generation, and provides supporting standardized trimming process guidelines, helping enterprises reduce post-processing costs and improve finished product quality.
