Introduction to hydraulic press for ballistic helmet and bulletproof helmet manufacturing

It is our honor to provide you with our services. Today, the Jianlong Hydraulic Technology Team will introduce you to a customized "hydraulic press for ballistic helmet and bulletproof helmet manufacturing". Welcome and thank you for your participation in comments and exchanges of opinions! Because we know that in the manufacturing process of ballistic helmets (bulletproof helmets), hydraulic presses are key molding equipment. It plays a very important role in the manufacturing process of helmets. It is mainly used to press composite materials (such as ultra-high molecular weight polyethylene, aramid fiber, carbon fiber or metal/ceramic hybrid materials) into ergonomic helmet shapes. Therefore, below we will briefly introduce the main role and key technologies of this hydraulic press in the helmet manufacturing process: 

1. The role of hydraulic press

1.1 Material preforming: Press multi-layer composite materials into the initial shape of the helmet (such as hemispherical shape) under high temperature and high pressure.

1.2 Precision molding: Through molds and precise pressure control, ensure that the density of the bulletproof layer of the helmet is uniform and avoid structural defects.

1.3 Lamination curing: Heat and pressurize the resin-based composite material to cure it and enhance the overall strength and bulletproof performance.

2. Key technologies and parameters

2.1 Pressure range: Usually 100~500 tons of pressure is required (adjusted according to the material and helmet grade).

2.2 Temperature control: Some processes require heating (such as 150~200℃) to cooperate with resin curing.

2.3 Mold accuracy: High-precision steel molds ensure that the curvature and thickness of the helmet meet the ballistic protection standards (such as NIJ standards, VPAM).

2.4 Automation system: Modern hydraulic presses integrate PLC control to achieve automatic adjustment of pressure, temperature and time.

3. Advantages

3.1 High consistency: Uniform hydraulic pressure ensures stable bulletproof performance of each helmet.

3.2 Complex curved surface molding: It can process complex shapes that conform to ergonomics (such as arcs, reinforcing ribs).

3.3 Adapt to a variety of materials: Compatible with polyethylene, aramid, fiberglass and mixed materials.
