Project Details

ABS Injection Mold for Consumer Product Housing

This project focused on the development of a custom ABS injection mold for a consumer product housing. The customer needed a plastic housing mold that could support sample confirmation and follow-up injection molding production.

Project Background

The housing part required both structural performance and appearance quality. It needed to fit with related components, maintain stable dimensions, and present a clean surface after molding.

Customer Requirements

The customer required a mold solution that could support:

– ABS plastic housing production
– Stable dimensions
– Clean surface appearance
– Proper assembly fit
– Controlled parting line and gate marks
– Mold trial and sample confirmation
– Mold modification before production

Mold Making Process

The project process included drawing review, DFM evaluation, mold structure planning, tooling manufacturing, mold trial, sample inspection, and mold modification.

Technical Focus

For ABS housing parts, key technical points usually include wall thickness, shrinkage control, gate location, ejection method, parting line design, surface texture, deformation control, and assembly fit.

Sample Confirmation

After mold trial, the molded samples were checked for appearance, dimensions, structure, and fit. Any issues such as flash, sink marks, warpage, or assembly mismatch needed to be reviewed before mold confirmation.

Project Summary

This case shows how plastic injection mold making supports custom ABS housing development. With proper mold evaluation, trial sampling, and modification, the mold can be prepared for stable injection molding production.

Manufacturing Process

Drawing and 3D File Review

The product drawing, 3D file, housing structure, wall thickness, assembly features, and appearance requirements were reviewed before mold planning.

DFM and Mold Structure Evaluation

The mold structure, parting line, gate location, ejection method, draft angle, and potential molding risks were evaluated before tooling.

Injection Mold Manufacturing

The injection mold was manufactured according to the confirmed mold structure and product requirements.

Mold Trial and Sample Production

Trial samples were produced to check the molded housing appearance, dimensions, assembly fit, and molding performance.

Sample Inspection and Mold Modification

The trial samples were inspected, and mold adjustments were made according to appearance, dimension, or assembly feedback.

Final Mold Confirmation

After sample approval and mold modification confirmation, the mold was prepared for follow-up injection molding production.

Secondary Processes

▹

Deburring

Remove small burrs or sharp edges from molded ABS housing parts after trial or production.

▹

Surface Texture / Appearance Checking

Check surface texture, color consistency, parting line, gate marks, sink marks, and visible appearance quality.

▹

Assembly Fit Checking

Check whether the ABS housing fits properly with related covers, buttons, inserts, or internal components.

▹

Packaging

Pack confirmed molded housing samples or finished parts with protective bags, foam, trays, or cartons.

Technical Challenges

The main challenge was balancing housing appearance, structural strength, and molding stability. For ABS housing parts, the mold design needed to control shrinkage, sink marks, flash, warpage, parting line visibility, gate marks, and assembly fit. The mold structure and molding conditions had to be adjusted based on trial sample results.
