Manufacturing Capabilities of Custom Smart Injection Molding Service


NameDescription
Rapid toolingMold working life time up to 20,000 runs. Short machined time.
Production toolingTraditional molds, used for mass production.
Single cavity mouldsMoulds only produce one part per cycle, mostly used for low production rates.
Multi cavities mouldsMoulds can produce more than one part per cycle, used to increase production rate.
Family mouldsMoulds produce two or more different parts per injection cycle, the parts should be of the same material and color.
Two plate mouldsMoulds consist of one parting plane which used for parts that are typically gated on or around their edge.
Three plate mouldsMoulds consist of two parting planes which used for parts that can be gated anywhere along its surface.
Insert moldingInserts are placed into the mold and molding occurs around them. This is allows for inserts such as helicoils to be molded in your design.
OvermoldingPremade parts are placed into the mold to mold over them. This is allows for multi-material injection molding.

FAQs of Prototype Injection Molding Manufacturing Services & Systems

Can I modify the injection mold after the first run?

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. If the changes are too great, however, producing a new mold may be more cost-effective than reworking the existing one.

Where is the tooling when my injection mold is done?

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.

Who owns the mold?

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