315 ton Kevlar aramid bulletproof helmet molding hydraulic press

This machine is a 315-ton four-column hydraulic press, which is a special equipment for pressing Kevlar bulletproof helmets, also known as a 315-ton Kevlar aramid bulletproof helmet forming hydraulic press. The main body of the machine adopts a three-beam four-column structure, which is simple and stable, and easy to load and unload. The equipment has three operating modes: manual, automatic, and semi-automatic. It can be switched with one button and is easy to operate; PLC control can accurately control the pressure and stroke, realize the process of fixed pressure and timing, and pressure and time maintenance, and can customize OEM heating molds for customers, providing one-stop service;

The 315-ton Kevlar aramid bulletproof helmet forming hydraulic press can adopt a hot and cold mold dual machine configuration. First, the cut aramid fiber sheet is pre-pressed on the hot mold. The pre-pressing pressure is generally 2000KN. The product is relatively soft, and then it is placed on the cold mold for pressing and shaping. The shaping pressure is generally 3150KN. The finalized product needs to undergo subsequent processes such as trimming and spraying to finally become a finished product.

Performance characteristics of Kevlar aramid bulletproof helmet forming hydraulic press :

1. The mainframe structure is computer optimized, and the four-column structure has good rigidity and high precision;

2. Use liquid as the medium to transfer energy, and adopt imported low-noise plunger oil pump;

3. Cartridge valve integrated system, reliable action, high cleanliness and low leakage;

4. Through the operation panel selection, two molding processes, fixed stroke and fixed pressure, can be realized;

5. Working pressure and stroke can be adjusted within the specified range according to process requirements;

6. The electrical appliance is controlled by PLC programmable program. The pressing actions are generally: slider down, deceleration and downward movement, slow pressing and forming (sometimes exhaust is required), pressure maintenance, pressure relief, slider slight return, fast return to the upper limit, ejection cylinder slow ejection, ejection cylinder fast ejection, ejection cylinder return, manual material removal and feeding.

7. The superior configuration of the main components of the 315-ton four-column hydraulic press greatly improves product reliability.

The production process of Kevlar aramid bulletproof helmets is to cut first, then put it on a press to cooperate with the mold to press and form. The molding process is heated. After molding, it is relatively soft and needs to be placed on another set of molds for final shaping. Therefore, the mold is divided into two sets of molds, hot molds and cold molds. The hot mold is used for molding, and the cold mold is used for final shaping. The hot mold is heated by an oil temperature machine, and the cold mold is finalized by a chiller. Therefore, two sets of molds are generally equipped with two sets of presses. After the later molding, other subsequent processes such as trimming are also required.
