EVA Bag Mold Manufacturer

EVA (ethylene-vinyl acetate copolymer) is a lightweight, durable and flexible material widely used in bags, footwear, electronic product protective cases and other fields. EVA bag mold is a mold used to produce EVA bags. Its precision and quality directly affect the appearance, dimensional stability and durability of the final product. As a professional EVA bag mold manufacturer, Fair Shine has a full set of processing equipment and assembly services, and is committed to providing high-quality mold Solutions.

EVA Bag Mold Manufacturing Equipment

Advanced processing equipment is required to manufacture high-precision EVA molds, including:

CNC Machining center - computer numerical control machine tools, to ensure high-precision mold processing and fine engraving of complex curved surfaces.

EDM electrical discharge machine - used to manufacture precision parts of high-hardness materials to improve detail performance.

Lathes and milling machines - used for preliminary processing of mold frames and structural parts.

Grinding machine - ensures the smoothness of the mold surface and improves mold accuracy.

3D scanners and testing equipment - ensure that the mold meets the design standards and improves assembly accuracy.

EVA Bag Mold Manufacturing Process

The production of EVA bag mold involves several key process links, including:

CAD/CAE design – Design the mold through 3D modeling software to ensure accurate dimensions and optimize the molding effect.

CNC Machining (CNC) – Use high-speed CNC machine tools to accurately engrave the mold to make its surface smooth and the details clear.

Electrical discharge machining (EDM) – Used to process complex details and improve the surface quality of the mold.

Heat treatment – Improve the hardness and wear resistance of the mold and extend its service life.

Polishing and surface treatment – Use sandblasting, electroplating, nitriding and other processes to improve the smoothness of the mold surface and optimize the appearance of EVA products.

Assembly and testing – After precise assembly and trial mold, ensure that the mold meets production requirements.

Material selection of EVA Bag Mold

High-quality EVA bag mold is mainly made of the following materials:

45# steel – Suitable for ordinary molds with average durability.

P20 mold steel – Has good polishing and wear resistance, suitable for mid-to-high-end molds.

H13 hot working die steel – has excellent high temperature resistance and is suitable for high-strength production needs.

S136 stainless steel – suitable for molds with high precision and high finish requirements, with strong rust resistance.

The choice of different materials depends on customer needs and product specifications. Fair Shine can provide the best material solution according to production requirements.

Precision and surface treatment of molds

The precision of EVA bag mold determines the quality of the final product. Fair Shine's mold processing accuracy can reach ±0.01mm, ensuring consistent product shape and perfect details.

Surface treatment methods include:

Mirror polishing – improves the finish of the mold and makes the surface of EVA products smoother and More beautiful.

Sandblasting – increases friction and improves the anti-slip and wear resistance of EVA products.

Nitriding – increases mold hardness, enhances wear resistance and extends service life.

Electroplating – increases the corrosion resistance of the mold surface and improves production efficiency.

Optimization of EVA Bag Mold Production

In the production process of EVA bags, mold optimization is the key to improving product quality and production efficiency. Fair Shine optimizes production in the following ways:

Mold flow channel optimization – through reasonable design of flow channels, ensure that EVA materials are evenly filled and defects are avoided.

Quick demoulding design – using special demoulding technology to improve production efficiency and reduce scrap rate.

Multi-cavity mold design – suitable for mass production, increase production capacity and reduce production costs.

Intelligent temperature control technology – control mold temperature, optimize molding effect, reduce deformation and bubbles.

Features of EVA Bag Mold and finished products

Using high-quality EVA bag mold can produce EVA bags with the following characteristics:

Lightweight and durable – EVA material is light but strong and easy to carry.

High elasticity and cushioning – provides good impact resistance and is suitable for protective bags.

Waterproof and moisture-proof – EVA has excellent waterproof performance and is suitable for outdoor use.
