Mobile Phone Case & Household Product | 3D Design Support

Product Overview

We provide OEM and ODM plastic injection mould manufacturing services for mobile phone cases and household consumer products.

With in-house 3D design and mold development capabilities, we support customers from concept design to mass production.
Our tooling and molding processes are suitable for precision plastic components made from ABS, TPU, TPR, and other common materials used in 3C and household products.

Whether you already have finalized 3D data or only an initial product idea, we offer technical support throughout the development process.

Application Areas

This plastic injection mould solution is widely used for:

• Mobile phone cases

• Protective covers and accessories

• Consumer electronic enclosures

• Small appearance-sensitive plastic components

These products require consistent surface finish, structural stability, and reliable mass production capability.

OEM & ODM Service Scope

We support two cooperation models:

OEM – Built-to-Print Manufacturing

• Production based on customer-supplied 3D files

• Strict dimensional and structural control

• Mold manufacturing and injection molding service

• Batch production according to order volume

ODM – Product Development Support

• 3D design and structural optimization

• DFM (Design for Manufacturability) review

• Material selection guidance

• Mold structure design

• Prototype validation before mass production

This flexible model helps brands reduce development time and tooling risks.

Key Engineering Focus

Plastic injection moulds for mobile phone cases and household products require attention to both appearance quality and production efficiency.

1) Surface Quality & Cosmetic Control

Mobile phone cases are visible consumer products. Surface defects must be minimized.

• Optimized gate design to reduce weld lines

• Controlled shrinkage to prevent sink marks

• Precision cavity polishing or texture finishing

• Accurate parting line control to reduce flash

Surface consistency is essential for market acceptance.

2) Material Compatibility (ABS / TPU / TPR)

Different materials behave differently in molding:

• ABS for rigid structures

• TPU for flexible protective covers

• TPR for soft-touch components

Runner design, gate type, and cooling layout are adjusted according to material characteristics.

3) Dimensional Stability & Fit

Phone cases must fit precisely to device models.

• Shrinkage compensation considered in mold design

• Stable shut-off and alignment system

• Tight tolerance control for snap-fit structures

• Trial molding and dimensional verification

Proper dimensional control ensures reliable assembly and user experience.

Technical FAQ

Q1: Can you develop a mold from an idea without a finished 3D file?
Yes. We support ODM development, including 3D design and structural optimization.

Q2: Do you provide injection molding after mold manufacturing?
Yes. We can provide both tooling and production services depending on project requirements.

Q3: How do you ensure phone case fitting accuracy?
Shrinkage compensation and dimensional verification are performed during mold design and trial molding.

Q4: Can flexible materials like TPU be supported?
Yes. Mold structure and runner design are optimized for flexible materials.

Q5: What is the typical mold lead time?
Usually 25–45 days depending on mold complexity.
