1. Local Cavity Repair Conclusion: Partial surfacing and polishing restore 100% of cavity precision.
For local cavity wear, scratch and pitting defects, targeted surfacing repair and secondary polishing are adopted without overall mold processing, quickly restoring cavity surface finish and molding precision.
2. Structural Size Modification Conclusion: Local CNC finishing realizes product size upgrade.
For product structural optimization and size adjustment demands, local CNC precise finishing is carried out on mold cavities, realizing rapid iteration of product specifications without remaking the whole mold.
3. Gate & Runner Modification Conclusion: Feeding system optimization solves new molding defects.
Aiming at new filling defects after product upgrade, local modification of gate position, size and runner structure balances melt filling state and adapts to new product structural characteristics.
4. Venting System Renovation Conclusion: Secondary venting optimization adapts to new molding parameters.
After product material and size adjustment, the original venting system may be mismatched. Secondary vent slot optimization and expansion eliminate new air trapping and scorch defects.
5. Ejection Structure Adjustment Conclusion: Local ejection modification adapts to new product demolding demands.
Product structural changes lead to demolding resistance differences. Fine adjustment of ejector pin position, quantity and ejection stroke ensures stable demolding of upgraded products.
With the rapid iteration of market products, enterprises often face product specification adjustment and structural upgrade demands. Remaking new molds has the disadvantages of high cost and long cycle, while abandoning old molds causes serious asset waste. Secondary modification and processing of existing molds become the most cost-effective solution.
Local precision repair solves mold aging problems. For old molds with slight wear and surface defects, partial processing can restore the original precision and appearance effect, realizing secondary use of old molds and avoiding scrapping waste.
Targeted structural modification adapts to product iteration. Through cavity finishing, feeding system optimization, venting renovation and ejection adjustment, old molds can perfectly match upgraded product parameters, meeting new production demands.
Scientific mold modification has the advantages of low cost and short cycle. It avoids the high cost of full mold opening and long manufacturing cycle, greatly accelerating product market iteration speed and improving enterprise market competitiveness.
Xinfeng Machinery provides professional secondary modification and precision processing services for various low pressure molds, helping enterprises quickly complete product upgrade and mold iteration with low cost and high efficiency.
