A concise overview of the part, manufacturing route, engineering considerations and delivery requirements.
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.
Production Route
Manufacturing Process
The project workflow is presented as compact engineering stages instead of one long vertical timeline.
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.
Finishing Support
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
How the Project Was Evaluated
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.
