Qiaolian machine is the brand for machinery of Siwarde group.We have been committed to the development and research of PC/ABS/PMMA sheet,silicone and rubber forming equipment more than 10 years.We have much experience in manufacturing compression molding machine,vacuum compression molding machine,rubber injection molding machine,LSR injection molding machine,extrusion machine,banbury mixer and mixnig mill machine,as well as related technologies.
Due to the low mold cost and short lead times, this also makes it very easy to modify the design of the parts.
Large parts can be manufactured, which can simplify a product that was originally composed of multiple parts into a single part, saving material costs and assembly costs.
A method of manufacturing open shell products using thermoplastic sheets. The plastic sheet is cut to a certain size for heating and softening, and with the help of the air pressure difference or mechanical pressure on both sides of the sheet, it is deformed and then overlaid on the specific mold contour surface, cooled and shaped, and the cutting edges are trimmed.
Two-sheet thermoforming uses two sheets, making it possible to produce a double-sided hollow box part with features on both sides.
Double sheet thermoforming expands the application of hot compression molding, and in some cases can replace rotational and blow molding to produce hollow box parts.
Due to the low pressure, the complex mold structure and expensive mold materials are not required, so the mold cost is low, the part cost is very competitive, and it is an ideal process for large part samples and small batch production.
Also known as vacuum forming machines, these machines heat plastic sheets until they are malleable, and then use vacuum to mold the plastic into molds. Once the plastic is formed and cooled, a stream of air separates it from the mold. Thermoforming machines are best suited for easy-to-form plastics such as ABS, polystyrene and PETG.
