A Plastic PVC Pipe Fitting Mold is a tool used in the manufacturing process of plastic pipe. This molding machine consists of two parts: an opening and a closing screw. The opening allows the plastic to flow into the mold while the closing screw forces the melted plastic into the cavity of the mold. Water or other cooling fluid passes through the mold cavity as the plastic is melted. Once the product has cooled, the part is removed from the mold.
The pvc is then bent using heat. While the heat must be sufficient to soften the pvc, it should not melt it. Also, the amount of pressure should be controlled to avoid overstretching the pvc outside the bend. Generally, a longer bend is better than a shorter one. A PVC pipe fitting mold can be used to produce a variety of shapes.
Among the many types of moulds used in the plastic part processing industry, the PVC pipe fitting mould is one of the most important. Apart from its high-quality material, this molding tool is corrosion resistant and can withstand strong acid and alkali. It also has excellent mechanical and impact resistance. This tool is used in manufacturing various types of PVC pipe fittings and pvc ball valve.
It is important to note that the process of producing PVC pipe fittings is much more complex than molding simple solid shapes. This molding technique requires multiple-part assembly, which requires an experienced mold engineer. Molds for larger pipe fittings are usually produced by other molding methods. However, smaller pipe fittings are usually produced using the injection molding technique.
PVC pipe fittings are produced by a process known as pipe fitting injection molding. This process involves heating and pressure-forming parts from an area of pipe. The fittings are manufactured up to 12 inches wide using this process. For fittings larger than twelve inches in width, the process is generally performed by machining a segment of pipe. Depending on the size, the pipe fitting mold may be in the form of a tee or elbow.
To make PVC pipe fittings, a proper temperature control system is necessary. To make sure the plastic does not become overly hot, a fan should be placed on the injection screw barrel or hopper to provide additional cooling. Moreover, the mold should have ample space for core pulling. For example, a Yusheng PVC pipe fitting molding machine is designed with a 200mm safety door distance on both sides.
