Silicone Curing Press

  • Solid silicone compound workIt is the machine for production from solid compound; injected liquid silicone is a different route.
  • The same hot press family as the melamine and rubber presses

What is a Silicone Curing Press?

The silicone curing press turns solid silicone compound into a finished part by vulcanising it under pressure in a heated mould. What is decisive is not force but the balance of temperature and time: the mould is heated zone by zone, and cure time and dwell under pressure are held in the recipe.

Is this press right for you?

Suitable

  • Shaping solid silicone compound by curing it in a mould

How solid silicone compound cures, and how it differs from injection moulding

Silicone parts are produced in two ways: solid silicone compound is cured by pressing it in a mould, while liquid silicone is injection moulded. This press is the machine for the first route — a measured charge of compound is placed in the mould, vulcanises under pressure between heated platens, and the finished part comes out of the mould. Although both routes use the same material, their machines, moulds and cost structures differ; stating at the outset which route you will produce by makes sure your enquiry reaches the right machine.

Silicone's curing window is narrower than that of most rubbers. Under-cured, the part stays tacky; over-cured, it turns brittle. Temperature and time are therefore tied to the HMI recipe, the mould is heated zone by zone, and thermocouple feedback corrects any deviation within the cycle.

In multi-cavity moulds — baking and cake moulds, gasket cavities — every cavity coming out at the same thickness depends on the parallelism of the platens. The closing profile also determines flash: a mould that closes too fast pushes material out, one that closes too slowly leaves air in the cavity.

The silicone curing press belongs to the same hot press family as the melamine and rubber presses. The frame, the heating infrastructure and the recipe logic are shared; what changes is the mould, the number of zones and the cycle time.

  • Zoned mould heating with thermocouple feedback
  • Cure time and dwell under pressure held in the HMI recipe
  • A platen arrangement that holds cavity-to-cavity thickness variation in multi-cavity moulds
  • Flash control through the closing profile setting
  • A shared frame family open to melamine and rubber work as well

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.
