How to improve the yield rate of rubber products during rubber compression molding?
Improving the yield rate of rubber products during rubber compression molding is a multi-faceted task that requires process adjustment, in-depth knowledge, and continuous monitoring. Here are some strategies:
Quality of Raw Material:
Always use high-quality raw materials. The homogeneity and properties of the rubber greatly impact the yield rate.
Optimizing the rubber Mold Design:
Design rubber molds with material usage in mind. Try to minimize waste in our rubber mold design while still achieving our customer’s needed product specs.
The Right Curing Method:
The curing process should be well-controlled. Over-cured rubber becomes brittle, while under-cured rubber may not hold its shape.
Proper Training:
The compression molding team have proper training to understand the process and monitor the machine effectively.
Know our compression Machines:
The performance of our rubber compression molding machine directly affects the yield rate. Ensure regular maintenance and periodic checks to ensure it’s in best working condition.
Process Control:
Monitor all the phases of the compression molding process from pre-heating until final curing. Consistently check machine parameters like temperature, pressure, and time.
Waste Reduction:
A significant way to increase yield is by reducing unnecessary waste. This involves reviewing your entire process to identify areas of potential waste, such as leftover material from cut-offs, and finding ways to minimize them.
Preform Design:
In rubber compression molding, designing an optimal preform (the rubber slug that is to be compressed) can help provide a balanced flow and reduce material wastage, which ultimately improves the yield rate.
Implementing ISO and Six Sigma Standards:
Quality management standards such as ISO and Six Sigma methodologies help implement process control techniques, reduce variation, and consequently improve yields.
Through continuous improvement and careful monitoring, we can optimise the yield rate of rubber products in the compression molding process. It might take some time, but it’s a worthy investment.
