As a one-stop rubber and plastic injection molding manufacturer, we will make the tooling by ourselves. As long as you continue to run parts in our facility, we will keep the molds for you and make any necessary repairs or refurbishments at our cost for the life of your mold.

The mold belongs to you. Zhongde is only responsible for saving the mold for you and will not use it for other customers.

We can modify your steel injection mold by additional machining, fill-in welding, welding in additional material, or inserting a replacement feature for a reasonable cost. However, if the changes are too great, producing a new mold may be more cost-effective than reworking the existing one.
