The female half of a plastic injection mold. It is the interior surface that shapes the molten plastic and defines the outer geometry of the part. Typically located in the stationary platen.
Read Definition →CoreThe male half of a mold. It forms the interior surfaces and hollow features of the part. Typically located in the moving platen and, together with the cavity, defines the full part geometry when closed.
Read Definition →Draft AngleA slight taper applied to vertical surfaces of plastic injection parts to allow clean ejection from the mold. Typical values range from 1° to 3°, though textured surfaces may require greater angles.
Read Definition →Sink MarkSurface depressions that form on plastic parts during cooling, caused by volumetric shrinkage in thicker cross-sections beneath the surface. Minimized by uniform wall thickness and optimized cooling channel design.
Read Definition →ToleranceThe permissible range of dimensional deviation. For plastic injection parts, general tolerances typically range from ±0.1 mm to ±0.5 mm, while tighter values may be applied in precision assembly zones.
Read Definition →Weld LineThe line formed in a mold cavity where two molten plastic flow fronts coming from different directions meet. Mechanical strength and surface quality can be reduced at the junction; minimized through gate placement design.

- What steels are used in mold manufacturing?
- 1.2311, 1.2738, 1.2344 (H13), and S136 can be evaluated based on project requirements, production volume, and part material. The right steel selection directly affects mold life and part surface quality.
- Single-cavity or multi-cavity mold — how to decide?
- The decision depends on production volume, cycle time, part size, and cost targets. Multi-cavity molds reduce unit cost in high-volume production, but require higher initial investment and precise balancing.
- What is a T1 trial?
- T1 is the first trial run after mold manufacturing is complete. It is used to verify part geometry, surface quality, and dimensional conformance. Required revisions are determined based on T1 results.
- Can existing molds be revised?
- Yes. Revisions arising from production issues, cavity addition for capacity increase, or geometry updates can be evaluated on a project basis.
- Can a hot runner system be designed into the mold?
- Yes. Hot runner system design and integration can be evaluated depending on project requirements and production volume.
