Especially for molds with small demoulding slope or with concave molds, at the same time, use the demoulding mechanism to bump or oscillate to demould, and sometimes apply mold release agent on the sh

Demoulding is to move the product out of the mold. Usually, whether it is a concave mold or a punch, in most cases, the product is close to the mold due to the cooling and shrinkage of the product, so

In order to improve production efficiency, vacuum forming products often need to be cooled before demoulding. Ideally, both the inner and outer surfaces of the part in contact with the mold are cooled

The pneumatic system can be composed of the molding machine itself with a compressor, an air storage tank, a workshop main circuit set, and a valve. The molding machine needs compressed air with a pre

The rotating power of the vacuum pump is determined by the size and molding speed of the molding equipment, and the equipment with larger or faster molding speed is usually as large as 2-4KW. The size

The vacuum system is composed of vacuum pump, air storage tank, valve, pipeline and vacuum gauge. In vacuum forming, a single type vacuum pump is often used. The vacuum degree of this pump should reac

One of the main processes in the vacuum forming process of thermoplastic sheets and films is sheet heating. The duration and quality of electrical heating depends on the structure of the heater, the t

The frame type clamping device consists of upper and lower frames. The sheet is sandwiched between the two frames. When the frame is open, the lower frame generally remains fixed. The lower part of th

When the plastic sheet is formed, the sheet is fixed on the clamping device. Clamping devices that are convenient for fixing sheets of various sizes are mostly used in thermoforming general-purpose an

Single male mold forming is also called punch forming or bending forming, vertical forming. It is a molding method in which the heated and softened plastic sheet is formed into a certain shape by mach

Dryer: The drying of compressed air is a relative concept. As long as there is a temperature change in the compressed air during use, there will be water precipitation. It's just the amount of water r

Filters: The number of filters and the location where they are connected to the compressed air system are also different according to the air quality requirements. The basic configuration is the filtr
