Molding type

One single male mold molding
Single positive molding is also called punch molding or bending molding, and is vertical molding. It is a molding method that uses machinery to mold heated and softened plastic sheets into a certain shape.
Single female mold molding
Single female molding is also called concave molding.
Three pairs of molds
The mold for molding is composed of a male mold, a female mold, a clamp and other accessories.
Composite molding
Function composition.
Clamping equipment
When the plastic sheet is formed, the sheet is held in place on a clamping device. Clamping devices that facilitate the fixation of sheets of various sizes are often used on general-purpose and composite thermoforming machines. Some have the entire molding machine equipped with a clamping frame.
Clamping devices can be divided into two categories: one is frame type and the other is split type. The frame-type clamping device consists of upper and lower frames. The sheet is sandwiched between two frames. When the frame is open, the lower frame generally remains fixed. The lower part of the upper frame of various types of single-station molding machines is directly fixed on the molding chamber. Manual and semi-automatic molding machines for loading parisons and removing finished products by hand, when the frame size is large, are equipped with safety operating devices within the frame opening range. For parisons with large slippage during molding, the clamping force is required to be adjusted within a relatively wide range. To this end, two rubber-covered rollers are used to press each other with springs and are equipped with a pressure adjustment device. The clamping of the continuous pull tab forming machine is the joint action of the zippers on both sides and the front and rear gates.
It is best to use automatic control for the clamping device so that it can act quickly and help improve the quality and efficiency of the parts.
Heating equipment
One of the main processes in the vacuum molding process of thermoplastic sheets and films is sheet heating. The duration and quality of electric heating depend on the structure of the heater, the thermal inertia of temperature heat transfer behind the radiating surface, the distance between the sheet and the heater, the radiant energy absorption coefficient, the characteristics of the heater surface and the thermophysical properties of the material. Commonly used heaters include electric heaters, crystal radiators and infrared heaters.
Vacuum equipment
The vacuum system consists of a vacuum pump, a gas tank, valves, pipelines, and a vacuum meter. In vacuum molding, a separate vacuum pump is often used. The vacuum degree of this pump should reach 0.07~0.09 Mpa (520mmHg) or above. The gas storage tank is generally a cylindrical box welded with thin steel plates, with an oval bottom. The capacity of the gas tank should be at least half greater than the capacity of the largest molding chamber. On the vacuum line, appropriate valves must be installed to control the narrow vacuum capacity.
The rotational power of the vacuum pump is determined by the size and molding speed of the molding equipment. Larger or faster molding speed equipment is often as large as 2-4KW. The size of the vacuum central system depends on the specific production and development requirements of the factory.
