Presses

Ballistic Plate and Helmet Press

  • Helmet and flat plate in the same familyThe dome form and the flat plate share the same curing logic; what separates them is the mould and the pressure distribution.
  • Pressure even across the plateA single weak area lowers the protection class; every point of the laminate must see the same pressure and the same temperature.
  • Hot oil heating and cooling, or electric heating with water cooling

What is a Ballistic Plate and Helmet Press?

The ballistic plate and helmet press cures protection plates, composite helmets and chest–arm–shoulder protection parts under pressure between heated platens. This press stands on the protective side: it produces the part that resists, not the offensive munition.

Laminate quality depends on pressure and temperature being distributed evenly over the surface; a single weak area lowers the protection class. The deep dome of a helmet and a flat plate run on the same press, with a different mould and a different pressure distribution.

For those who want the detail

How it works: lamination, the protection side and what makes helmets different

A ballistic protection part is produced by turning a layered preform into a single body under heat and pressure. The air between the layers is driven out, the resin flows, the section is compacted and the laminate cures. The protection class is determined as much by how evenly pressure and temperature are distributed over the plate surface as by the number of layers: a single weak area lowers the class of the whole plate.

A helmet is a different engineering problem from a flat plate. In a deep dome form, pressure and temperature have to be carried to every point of the layered preform at the same time; the mould and the pressure distribution are built accordingly. Helmets and flat plates stand together on this page because the machine family and the curing logic are the same.

Mould heating is done in two ways: a hot oil circuit both heats and cools; with electric resistance heating, cooling is handled by a separate water circuit. The dwell time under pressure determines the cycle.

The scope distinction matters: this press works on the protective side — helmets, chest protection, arm and shoulder protection. Ammunition cases and similar metal forming work belong to the offensive side and are done on deep drawing presses. One final note: ballistic performance is proved not by the press but by ballistic testing at an accredited laboratory. The press produces a repeatable laminate; the test provides the class certificate.

Rigid frame joined with prepared weld bevels

Across ÖZKOÇ — not a feature unique to this press

When the form or the embossing does not come out, the toolmaker is blamed straight away. More often than not the die is not the cause: the press frame deflects under load and the two halves of the die no longer seat fully on each other. The share the frame has in this is usually unknown on the buyer's side, because it is written in no catalogue.

When ÖZKOÇ builds the frame as a welded construction, it joins the crossbeams and the plates BY PREPARING A WELD BEVEL. There are many companies in the sector that join without preparing a bevel; the weld then stays on the surface only. Once the bevel is prepared, the weld penetrates the cross-section and the frame resists deflection under load.

This holds for every frame type, monoblock or column-type — it is not an option that depends on the type of press, it is ÖZKOÇ's manufacturing discipline.

  • Crossbeams and support plates are joined with a prepared weld bevel.
  • The weld does not stay on the surface, it penetrates the cross-section; the frame does not deflect under load.
  • The same discipline is applied whether the frame is monoblock or column-type.

Ram parallelism system

Across ÖZKOÇ — not a feature unique to this press

On wide and asymmetric parts the load bears on one corner of the ram; the ram comes down slightly tilted and one corner of the part turns out thicker than the other. The result: excess material, uneven strength, unnecessary heat and cycle time.

In the ram parallelism system designed by ÖZKOÇ itself, four counter-pressure cylinders bring the ram down parallel to the lower plate. The difference in thickness between the corners drops to a minimum; material is saved, and the homogeneity of the part keeps the strength where it is wanted.

The same arrangement works in cutting as well: at the instant the shear occurs, the counter-pressure cylinders absorb the shock, maintain parallelism and extend the life of the cutting die.

  • Four counter-pressure cylinders bring the ram down parallel to the lower plate.
  • On a wide and asymmetric part the difference in thickness between the corners drops to a minimum.
  • Material savings + homogeneous strength.
  • In cutting it absorbs the shock and extends die life.
