Plastics Tooling

Shape Point can deal with any production plastic material that your project requires. With over 20 years of plastic tool molding experience, we produce tooling that is error-free and budget-friendly.

Our engineers go over your designs before we open the tool to make sure that we avoid potential problems that can arise. Our molding expertise helps you save money down the long-run.

The most common tooling material options are below. Contact us if you have any special requirements.

“ShapePoint was helpful in taking our initial rough concept and improving on it. They were able to produce working units in just two months. This was quite a quick turnaround time for the complexity of the IoT product. We’ve used other vendors in the past and it took twice as long and was at least twice as expensive. Keep up the great work Shape Point!”

Lukas J.Concept to Mass Production in 2 months!

“ShapePoint has truly performed in the top 3% of the suppliers we’ve worked with. They meet deadlines and deliver excellent work in a cost-effective manner. Their Western project managers are a big asset as they improve communication and eliminate the chances of error that arises when dealing directly with Chinese factories.”

Michael M.Performance in the top 3%

“We’ve been using ShapePoint since 2006 now. Production quality has always met our expectations and there are low defective rates. When issues do arise, Shape Point gets on it immediately and rectifies it so it doesn’t happen again. We look forward to working with Shape Point for many more years to come.”
