Cookware presses

What matters when choosing a press?

Deep Drawing Press

• Adjustable speed and blank holder forceDrawing speed and counter-holding force are set to suit the part in order to keep wrinkling under control. As the sheet gains depth, material builds up at the edge; the blank holder holds it down and eliminates wrinkling.
• Blank holder pressure is decisiveIf the pressure is too low the sheet wrinkles, if it is too high the flow is choked and the part tears; the window between them is narrow.
• Seamless vessels and bodies, multi-stage drawing

Hydraulic Forming Press

• Single-acting · no blank holderThere is no counter-holding; the form is not deep and there is little or no wrinkling — a blank holder is not needed.
• Shallow forming, bending, embossing, coiningAs long as the depth of the shape stays shallow the job is finished with a single action and no cushion setting is required.
• A frame that does not deflect is decisiveIf the frame deflects the embossing does not come out fully, and the die gets the blame.
• Standard sizes and tonnages

Coining Press

• Work hardening through cold coiningThe grain structure is compacted and the yield strength rises; the part comes out stronger.
• A rigid frame at high tonnageA frame that deflects loses the dimension and wears the die.
• Shock-free force transitionsApproach, coining and decompression pass smoothly through a proportional valve; there is no impact.

Hydraulic Casting Press

• It works with an open mouldNo air bubbles are trapped inside the aluminium.
• Half the tonnage of die castingThere is no need to push molten metal through narrow channels; mould cost and floor space also come down by half.
• Around 1% scrap rateThe scrap rate for the same job in die casting is in the tens of per cent.
• A design developed by Özkoç itself

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

Melamine Press

• Thermoset curing, no way backA cured part cannot be remelted; quality is determined not by force but by thermal discipline.
• Zoned heating and degassingIf the volatiles formed in the compound are not vented, blisters and porosity are left on the surface.
• Two-daylight toilet seat arrangementOn a large, asymmetric seat a ram that descends parallel holds thickness and flatness.
• The same hot press family as the silicone and rubber presses

Hydraulic Cutting Press

• Cutting is the real purposeBending and flange trimming are done on the same press too; but the machine is built for cutting.
• The counter-pressure cylinders take the shock, not the frameAt the end of the cut the counter-pressure cylinders come in and absorb the sudden release of load.
• The compact alternative to a mechanical pressAt high tonnage the frame of a mechanical (eccentric) press grows and becomes expensive; a hydraulic press does the same job in a smaller package.
• Longer die life, cleaner cut edgeThe counter-pressure cylinders also help parallelism, and the impact does not pass into the die.

Hydraulic Transfer Press

• One finished part per press strokeAll the steps are pressed in the same cycle; the part is passed automatically between stations.
• No press, operator or die per stepOne machine gathers work spread over separate presses; intermediate handling and work in progress disappear.
• Not just a press, an automation lineThe trimming, cutting and piercing needed between the steps are applied on the same line.
• With sheet cutting or blank feeding, loading and transfer units
