Composite bulletproof helmets are generally made of fiberglass fabric, Kevlar fiber fabric, and thermoplastic resin. It includes a waterproof layer, fireproof layer, aramid fiberless fabric layer, and resin layer. 315-ton hydraulic press for compressing bulletproof helmets is specially designed for producing PE/Kevlar/Aramid fiber bulletproof helmets. It uses high-pressure processing technology to ensure the helmet material has sufficient protective properties. This helmet press can produce high-quality bulletproof helmets to ensure the safety of equipped troops.

This hydraulic press for compressing bulletproof helmet designed and produced by Zhengxi Hydraulic is used for forming convex hull bulletproof helmets. It can effectively avoid cracking caused by local forming, achieve negative angle forming, improve the forming quality, and ensure uniform thickness of the helmet after forming. Through reasonable selection and configuration of materials, combined with 315-ton press processing technology, the bulletproof helmet produced has good anti-hit performance and safety, and it can effectively protect the wearer’s head from external impacts.

According to the material and specifications of the helmet, 315-ton, 450-ton, 500-ton, 630-ton, 800-ton and other four-column hydraulic presses can be used.

Structural Features of Hydraulic Press for Compressing PE Bulletproof Helmet:

1. The host structure is optimized and designed by a computer. The four-column structure has good rigidity and high precision.
2. Use liquid as a medium to transfer energy. An imported low-noise plunger oil pump is used.
3. Cartridge valve integrated system, reliable action, high cleanliness, low leakage.
4. Through the operation panel to select, two molding processes of fixed stroke and fixed pressure can be realized.
5. Working pressure and stroke are adjustable within the specified range according to process needs.
6. Professional cylinder sealing components, strong reliability, and long life.
7. The automatic lubrication device of the guide rail fully protects the guide column and maintains accuracy.
8. The electrical system is controlled by PLC, which can realize one-key operation. The process is simple and easy to operate.

PE Bulletproof Helmet Molding Steps:

(1) Cutting: Cut the weft-free fabric of ultra-high molecular weight polyethylene fiber or film into circular sheets and laminate them.
(2) Helmet blank preparation: The weftless cloth circular sheets obtained in step (1) are laminated and cold-pressed in a mold to obtain a helmet blank.
(3) Preform preparation: Place the helmet blank in the preform mold, gradually shape the helmet blank, and gradually trim excess material on the outer edge of the blank.
(4) Preparation of molded parts: Put the preform obtained in step (3) into a mold to shape the preformed helmet, take it out after cooling, and obtain a semi-finished helmet.
(5) The semi-finished helmet is processed through trimming, painting, hanging, and other processes to obtain the finished helmet.

This PE bulletproof helmet press machine we produce adopts a 315-ton pressure design and has strong processing capabilities. It compresses helmet material into a shape that meets standard requirements. The press structure is strong and stable to ensure it will not be deformed or damaged during production. The press is also equipped with an advanced control system that can achieve precise pressure and temperature control to ensure that the processing of helmet materials meets requirements and improves production efficiency.
