BMC Secondary Block Compression Mold

This BMC Secondary Block Compression Mold is designed for a compact 111 × 38 × 41 mm electrical component using a single-cavity structure and HHP20 mold steel.

For compact electrical components, small dimensional differences can affect assembly, positioning or interchangeability. SET MOLD therefore focuses the tooling review on the functional features of the component rather than treating all dimensions with the same priority.

Precision Tooling for Electrical Assembly Parts

For similar secondary blocks, the engineering team can work from your 2D and 3D data to identify:

• Functional datum surfaces
• Critical holes and locating features
• Mating dimensions
• Tight positional tolerances
• Flash-sensitive areas
• BMC shrinkage compensation
• Features requiring CMM verification

SET MOLD's in-house inspection capability includes CMM, profile projection and height measurement, while dimensional and visual checks are carried out during the manufacturing process.

More Than an Individual Mold

If this secondary block belongs to a larger electrical assembly, send the assembly drawing together with the individual component drawing.

SET MOLD can review how the molded component fits surrounding parts and identify which dimensions should be controlled during mold manufacturing and T1 approval.

This approach is particularly useful when several BMC components must remain interchangeable after production.

Send your BMC electrical component drawing for tooling review and quotation.
