As a professional eva case manufacturer, GAODA follows a structured and repeatable manufacturing process to ensure consistent quality, predictable lead time, and reliable delivery for OEM and ODM customers.

Our EVA case manufacturing process is designed to support both small-batch projects and long-term mass production programs.

Step 1: Requirement Analysis & Product Evaluation

Every project starts with a detailed requirement review.

Our engineering team evaluates:

• Product dimensions and weight

• Protection level requirements (shock, pressure, vibration)

• Application environment and usage frequency

• Branding, appearance, and functional needs

This step ensures the EVA case structure is engineered specifically for the product, not adapted from a generic design.

Step 2: EVA Structure & Foam Insert Design

Based on the evaluation, GAODA designs the EVA case structure and internal foam layout.

Key considerations include:

• EVA hardness and thickness selection

• Shell structure and load-bearing areas

• Foam insert density and cutting method

• Internal organization and component positioning

As an experienced eva foam case manufacturer, we focus on balancing protection, weight, and cost efficiency at the design stage.

Step 3: Prototype Sampling & Functional Testing

GAODA produces a custom EVA case sample for verification.

During sampling, we:

• Validate product fit and protection performance

• Test foam insert stability and usability

• Review appearance, logo placement, and finishing details

Typical sample lead time is 3–7 days, allowing customers to review and confirm the design before mass production.

Step 4: Mass Production & Quality Control

After sample approval, the project enters mass production.

Production includes:

• EVA thermoforming and hot-press molding

• Foam insert cutting and assembly

• Case assembly and finishing

Quality control is conducted at multiple stages:

• Raw material inspection

• In-process quality checks

• Final inspection before packing

This standardized process ensures stable quality across every production batch.

Step 5: Packing & Global Delivery

Finished EVA cases are packed according to export requirements and customer specifications.

GAODA supports:

• Bulk packing or individual packaging

• Export documentation preparation

• Global shipment from China or Vietnam

With dual factories and international logistics experience, GAODA ensures on-time delivery for global customers.

A Manufacturing Process Built for Long-Term Cooperation

This structured manufacturing process allows GAODA to support:

• OEM brands with strict specifications

• ODM projects from concept to mass production

• Long-term programs with consistent quality

By working directly with a professional eva case manufacturer, customers reduce risk, improve efficiency, and build a stable supply chain.
