Custom Gradient IMD Phone Case

Product Overview

The Custom Gradient IMD Phone Case combines vibrant decorative effects with reliable everyday protection. Manufactured using in-mold decoration technology, the printed film is integrated into the case during molding, helping protect the artwork from fading, peeling, and surface wear.

As an experienced OEM phone case manufacturer in China, SENWEI provides custom colors, patterns, materials, structures, logos, packaging, and model development for mobile accessory brands, wholesalers, distributors, and promotional product companies.

Whether you need an existing design or a fully customized phone case, our engineering team can support your project from design review and prototyping to tooling, injection molding, assembly, quality inspection, and mass production.

Key Features

1. Vibrant Gradient IMD Design

The smooth purple-and-green gradient creates a distinctive and premium appearance. Colors, patterns, artwork, and visual effects can be customized according to your brand identity or product collection.

Unlike ordinary surface printing, the decorative layer is integrated into the case structure through the IMD process, providing a cleaner and more durable finish.

2. Long-Lasting In-Mold Decoration

In-Mold Decoration technology places the printed film inside the mold before injection molding. The artwork is then bonded with the molded component during production.

This process helps protect the design against:

• Color fading
• Pattern peeling
• Surface scratching
• Daily abrasion
• Moisture exposure

IMD is suitable for brands that require consistent graphics and efficient mass production across multiple phone models.

3. Reliable Drop and Scratch Protection

The phone case is manufactured from selected protective materials to help reduce damage caused by everyday drops, scratches, and impacts.

Depending on the required protection level, the structure can be customized with:

• Shock-absorbing TPU edges
• Rigid PC back panels
• Reinforced corners
• Raised screen edges
• Raised camera protection
• Air-cushion corner structures

The final construction can be adjusted according to your target market, retail price, and drop-test requirements.

4. Slim and Lightweight Construction

The case provides practical protection while maintaining a slim profile. Its lightweight construction makes the phone comfortable to hold and convenient to carry without adding unnecessary bulk.

Case thickness, edge height, corner reinforcement, and material hardness can be adjusted during product development.

5. Comfortable Anti-Slip Grip

The carefully designed side frame provides a secure and comfortable grip, helping reduce accidental drops during daily use.

Optional surface finishes include:

• Smooth finish
• Matte finish
• Fine-texture finish
• Soft-touch coating
• Anti-slip side texture

6. Precise Fit and Responsive Buttons

Each case is developed according to the dimensions of the specified phone model. Accurate cutouts provide convenient access to the charging port, speakers, camera, microphone, and other functions.

The button areas can be customized with independent buttons, integrated TPU buttons, metal buttons, or decorative color-matched buttons.

7. Customizable for Different Phone Models

We can manufacture custom IMD phone cases for a wide range of smartphone models, including selected Apple iPhone, Samsung Galaxy, Google Pixel, and other devices.

Please send us your required phone model list so our team can confirm available molds or evaluate new tooling requirements.

IMD Phone Case Manufacturing Process

1. Project Requirement Review

We review your required phone models, design concept, target market, estimated order quantity, materials, protection requirements, and packaging specifications.

2. Engineering and DFM Analysis

Our engineers evaluate the case structure, wall thickness, draft angles, button design, camera protection, assembly method, and IMD film positioning.

3. Artwork and 3D Confirmation

The artwork layout and 3D product structure are prepared for customer approval before tooling or sampling begins.

4. Prototype Development

Prototypes can be produced to check the product dimensions, appearance, grip, button response, and compatibility with the device.

5. Mold Making and Trial

For new structures or unsupported phone models, we manufacture the injection mold and conduct mold trials to optimize fit, appearance, and molding stability.

6. IMD Film Preparation

The customized artwork is printed, formed, and accurately positioned inside the injection mold.

7. Injection Molding and Assembly

The decorative film and case material are integrated during molding. Additional components such as buttons, camera bezels, or magnetic rings are assembled according to the approved specification.

8. Quality Inspection and Packaging

Finished products are inspected for appearance, dimensions, fit, artwork alignment, color consistency, and functional performance before packaging and shipment.

Quality Control

Quality control is carried out throughout material preparation, printing, molding, assembly, and final packaging.

Typical inspection items include:

• Incoming material inspection
• Artwork and color verification
• IMD film positioning
• Product dimension inspection
• Phone fitting inspection
• Button response testing
• Camera and screen clearance inspection
• Surface scratch and abrasion testing
• Adhesion inspection
• Drop testing according to project requirements
• Magnetic pull-force testing when applicable
• Packaging and shipment inspection

Inspection standards and test methods can be agreed upon before mass production.
