Evaluating Mould Machining and Assembly as One Process

Finished mould photographs show the completed tool, but supplier evaluation also needs a discussion of how its components are made and brought together. HAWEN's published manufacturing information covers machining, assembly and inspection. The applicable steps and supporting records should be confirmed for the individual design.

Look at the Relationships between Components

A mould box, tamper head and forming components need to be considered as a set. Ask which drawing references define their relationship and how changes to one component are carried into the assembly documentation. This is particularly useful when a project combines a new forming profile with an existing machine interface.

Discuss the proposed sequence for machining, any specified treatment and subsequent assembly. The purpose is to understand where important dimensions will be checked and who will resolve a discrepancy. Equipment names alone do not answer those questions, and a general workshop photograph does not establish the requirements of your particular order.

Questions for a Manufacturing Review

• Which approved drawings identify the parts and assembly revision?
• Which mating features and working surfaces require project-specific attention?
• What inspection information can be agreed for the completed tooling?
• How will a proposed design change be recorded and approved?

Keep the discussion focused on the mould being purchased. Request relevant examples or records where available, and identify any documentation that must form part of the agreed supply scope. A clearly defined assembly review is more useful than assuming that a familiar process name guarantees a particular result.
