The basis for determining precision injection molding is the precision of the injection molded product, that is, the dimensional tolerance, shape tolerance and surface roughness of the product. There are many relevant conditions for precision injection molding, and the most essential are the four basic factors of plastic materials, injection molds, injection molding processes and injection molding equipment.
When designing plastic products, engineering plastic materials should be selected first, and engineering plastics capable of precision injection molding must use materials with high mechanical properties, dimensional stability, good creep resistance and environmental stress cracking resistance. Secondly, the appropriate injection molding machine should be selected according to the selected plastic material, the dimensional accuracy of the finished product, the weight of the part, the quality requirements and the expected mold structure. In the process of processing, the factors affecting precision injection molding products mainly come from the precision of the mold, the shrinkage of the injection molding, and the variation of the ambient temperature and humidity of the product.
Q. What type of plastic is best for my design/component?
A. Materials selection depends on the application of your design and its working environment requirement. We will be happy to discuss the alternatives and suggest the best material.
Q. What type of mould tool do I need?
A. Mould tools can be either single cavity (one part at a time) or multi-cavity (2,4, 8 or 16 parts at a time).Single cavity tools are generally used for small quantities, up to 10,000 parts per year whereas multi-cavity tools are for larger quantities. We can look at your projected annual requirements and recommend which would be best for you.
Q.Ok, I've decided to go ahead with my project. How long will it take to get my parts?
A. It can take 3-6 weeks to have the mould tool manufactured depending on the part's complexity and the number of impressions (single or multi). After we have received final approval by you of the new tool, you can expect delivery of parts within 3-5 days.
