Can thin internal sections of the thermal block cause mold problems?

Can thin internal sections of the thermal block cause mold problems?

Yes. Complex or thin internal sections can increase the requirements for filling, compaction, core strength, wear control and demoulding. HAWEN therefore evaluates the proposed thermal block geometry before finalizing the mould structure. The review concerns how the complete block section can be formed, not just whether its outside dimensions fit the mould frame.

Show the complete internal layout

Provide a section drawing that identifies narrow webs, internal openings, changes in section and any insulation-related features. These details help explain where material has to enter and which forming elements define the finished shape. If the drawing is being revised, mark the changes so the proposed structure can be compared with the current product.

Do not assess a thin section from a single photograph or from one overall block dimension. The relationship between adjacent cavities, the product height and the intended release direction also needs to be understood. A reference sample can support that discussion, but it does not replace the full geometry.

Connect the drawing to the production conditions

Include the machine model, pallet dimensions, present mould layout and available information about the material and production process. If breakage or wear is already occurring, describe its location and when it appears in the cycle. This gives the technical review a defined problem to assess without assuming that a thinner section is either automatically feasible or automatically unsuitable.
