High-Pressure Forming Machine Features: Touch-Screen Control, Encoder Positioning and Safety

Below are the main features of the high-pressure forming machine described in the original article, grouped by control, positioning, safety and heating.

Control and display

• Temperature shown and set on the touch screen.
• Hydraulic pressure, opening and closing speed, intermediate stop position and baking time are displayed and set on the touch screen; pressure-holding function.
• Reserved interfaces for a robot, pneumatic control of an external heater plate and a safety door.

Positioning and mold sensing

• Rack encoder for position feedback, repeatability ±0.02 mm.
• Four sensing probes each on the upper and lower mold, shown on the display.
• Vacuum on both upper and lower side with settable vacuum-on and suction times.

Safety

• Safety light curtain.
• Pneumatic safety device that prevents the upper mold from falling.
• Safety valve on the operating side with proximity switch.

Heating and parameters

Heating is split into two sections, each with four independently controlled groups of 2 kW at 220 VAC. One model in the original article has a clamping force of 100 t and a gas pressure of 30 kg/cm². Current specifications are on the SANSEN product pages or in a quotation.

Forming results

According to the original article, composite corners do not whiten or delaminate, brushed stainless-steel films do not crack, and IML parts can be wrapped around the edges in one forming step.

Current model: AS201F-G high-pressure gas forming machine. How high-pressure forming differs from hot pressing: IMD/IML thermoforming machines: process and applications.
