Platen Press - Hot Press

Application:

Testform Laboratory presses are often used to prepare samples for different kinds of lab tests. This is because many labs testing equipment can only provide reliable results on the condition that the samples are properly pressed first.

The Testform Laboratory Presses’ series is an important tool for the preparing of samples with reproducible characteristics.

Uniform temperature distribution over the platen Surface and mechanical solidity to ensure constant thickness of the sample and consistent closure force are basic elements to ensure this result.

Testform Presses’ series is recommended for all demanding quality control and R&D applications where accuracy and consistency are prerequisites.

Features:

• Mechanical structure with 4 columns (with 60 mm diameter) 
• Hi-speed heating
• Touch-screen display for complete machine control

Cooling system with Water circuit:

The cooling of the press platens during the molding cycle is necessary for the molding of thermoplastic materials because the material must be cooled down to the solidification temperature before opening the mold.

Testform presses can be equipped with an efficient cooling device that allows the temperature reduction of the platens at a controlled speed (down to -30°C/min).

The cooling device consists of a cooling circuit that can be connected to a demineralized water supply source or to a chiller.

Moulds for Laboratory Press

Various kinds of moulds are produced for the preparing of samples by compression moulding according to the international standards.

Moulds are made with steel for moulds and produced by Testform mechanical workshop.
Most models of mould are chrome plated to ensure long duration and easy extraction of the samples

Moulds for plates

The molds for the preparation of plates are produced with the utmost care to ensure the maintenance of the required thickness and a perfect surface finish. For this purpose, the surface of the mold is ground and subsequently chromed. Standard molds have a size of 200x200 mm and a thickness of 2-, 4- or 6-mm.

Molds with dimensions and thicknesses different from the standard ones and with multiple thicknesses are produced.

Other Moulds

Other Molds are produced according to the specific needs of the customer.
