China polycarbonate injection molding

China is a reliable place to go if you are looking for reliable polycarbonate injection molding suppliers.

We’ll give you some tips on finding a reputable supplier and getting the most favorable deal.

China Suppliers: How to Find a Reliable One

You should keep a few things in mind when choosing a polycarbonate injection molding supplier in China. Research and asking around for recommendations are the first steps you should take.

Businesses can find good Chinese suppliers online through various forums and websites. You should contact a few potential suppliers and ask them about their experience, prices, and shipping times once you’ve identified a few potential suppliers.

If you are not sure about the quality of their work, you should also request samples.

Establishing a good working relationship with your supplier is crucial once you have chosen one. Communicate clearly, pay on time, and be clear about your expectations.

You can find a reliable polycarbonate injection molding supplier in China by above these tips.

Why those important for injection molding cost

injection molding cost
  • Part size- bigger parts mean a bigger mold, which means that bigger steel will increase the steel cost for the injection mold.
  • Part design- the more complex a part is, the more detailed the mold has to be. Some complicated parts will require special features to be added, such as lifters or sliders. Therefore, you should be open to advice from your mold maker and see if there’s anywhere that you can alter the part design to save on injection mold costs.
  • Materials: Depending on the part material of choice, the injection mold will have to be made of a particular material. For instance, if corrosive plastic-like PVC is to be used, the mold will have to be stainless steel to avoid any damage, ultimately bump the price up.
  • Part finish requirements- where parts have high gloss surface requirements, then more expensive steel and precise technical polishing will be vital, adding to the price.
  • Production volume- higher volume molds need more cavities, and so the mold will be larger. They also require a higher steel grade to last for longer, which impacts the injection mold cost.
  • Country of manufacture- different countries have different wage rates. If your mold is made in a country where labor costs are low, then you’ll naturally save money. In China, the average cost of an injection mold is around 40% less than in western nations.
