The cost of raw materials directly affects the total cost of injection molded products. Reasonable selection of raw materials, especially some recycled materials⁵ with good performance or alternative materials, can effectively reduce the cost of raw materials. At the same time, strict control of the amount of material used to avoid waste is also the key to reducing costs.

For example, avoiding the waste of excess materials through precise proportioning and usage calculation. In the process of injection molding production, recovering waste materials for recycling and reuse can not only reduce production costs, but also reduce the burden on the environment.

Materials: Choose Materials with Lower Processing Energy Consumption.

When choosing materials, go for the ones that use less energy to make the same thing. If you can get the same performance and save money, use the ones that flow better so they’re easier to make.

Please note that the materials provided by different suppliers may have different process characteristics and should be adjusted accordingly.

When drying and processing the material, dry it as you use it to avoid wasting energy by having the material get wet again after you dry it.

Store materials properly to prevent impurities or foreign objects from mixing in and ensure product quality. Some products can be recycled by adding the right amount of recycled material, but we need to be careful about storing and keeping the recycled material clean to avoid defects from dirty material.
