About small molds

tkb plastic injection parts, including mold design, mold production. We have in-house mold design and mold flow analysis, thanks to the latest 3D CAD/CAM software.

The lifespan of an injection mold ranges from hundreds to over a million times. The life of an injection mold depends on its environment, maintenance, construction and other factors.

What factors affect the durability of plastic molds?
Factors that affect the durability of plastic molds include environment, materials, maintenance, molding conditions and structural design. Injection mold life is the total number of molding cycles a mold can withstand before it fails. Failure here refers to any deformation that affects the quality of the part produced.

Surface treatments naturally show signs of wear earlier than most molds.

Certain factors affect how quickly this wear occurs, both at the surface level and in the overall design of the mold.

Due to the improved efficiency, proper mold structure design prolongs the service life of the mold. This includes designing efficient gating systems and cavities.
