4+4-Cavity Injection Mold for Top and Bottom Housings

UTTMould handled mold design, manufacturing, trials, small-batch trial production and export for a top-and-bottom plastic housing project. The mold was accepted and delivered. The project illustrates how tooling specifications, trial samples and inspection activities connect within an export mold project.

Project at a Glance

Material and shrinkage values above are tooling specification inputs, not measurements of the finished parts. Customer names and internal project identifiers are omitted.

Tooling for Paired Housing Components

The project specification calls for a combined mold with four top-housing cavities and four bottom-housing cavities. It records requirements for the molding material, shrinkage allowance, gating, ejection, surface finish and machine compatibility.

For buyers sourcing an injection mold from China, a specification of this kind helps define the requested tool before manufacturing. Design inputs should remain distinct from acceptance evidence: a shrinkage allowance informs tool design, while inspection records document the results obtained from molded samples.

Manufacturing, Mold Trials and Small-Batch Trial Production

UTTMould's confirmed scope covered the mold from design and manufacturing through trials and small-batch trial production. The project photographs include the tool installed on a molding machine and samples of the two housing components.

This scope links the tool build with the first molded parts, rather than treating mold manufacture as a standalone handover. Buyers planning a similar project can review UTTMould's mold manufacturing services and mold trials and injection molding production.

Sample Measurement and Mold Acceptance

The project records include a digital indicator with a contact probe positioned on a molded housing sample.

For a documented dimensional check, the reading needs to be associated with the measured feature, reference setup, drawing requirement and permitted variation. The photograph does not establish those details, so it is presented as a record of inspection activity rather than a claim about wall thickness, flatness or dimensional capability.

UTTMould confirmed that the mold was accepted and delivered after its work on the project. Actual cycle time, accumulated mold life and production yield are not reported here because supporting operating records are not included in the published case materials.

Preparing a Similar Project for Quotation

For a top-and-bottom housing mold, prepare:

• CAD files for both components and the relevant assembly information.
• The specified resin and any color or surface requirements.
• Critical dimensions and their acceptance criteria.
• Sample, trial-production and anticipated production quantities.
• Receiving-machine interface requirements for an export tool.
• The required trial, inspection and handover documents.
