Plastic Pump(KEXON) processing technology is actually quite strict, formal manufacturers actually have their own strict processing methods, there are many issues in the Plastic Pump processing should pay attention.
First, in the design of extruded plastics, if the material is high-density polyethylene or polypropylene, the cross-section of the Plastic Pump should be rectangular or elliptical. When the material is low-density polyethylene or other flexible material, its cross-section A round shape is preferable because it facilitates the extrusion of the contents from the Plastic Pump. The plastic parts used in conjunction with Plastic Pumps and mouths are mainly bottle caps and sealers. The design of the bottle mouth should be considered with emphasis, so that the Plastic Pump mouth can be better matched with the cap and sealer. The bottom of the Plastic Pump is the mechanical properties of the Plastic Pump. Weak parts. Therefore, the bottom of the Plastic Pump is generally designed to be concave. Plastic circular corners and recesses are made with large arc overs. In order to facilitate the stacking of Plastic Pumps and increase the stacking stability of Plastic Pumps, the bottom of Plastic Pumps should be designed with inner grooves.
Second, when the surface of the Plastic Pump is labeled, try to make the surface of the label flat. A "sash" can be designed on the surface of the Plastic Pump so that the tag can be accurately positioned without movement. During blow molding, the place where the parison inflates first contacts always tends to harden in advance. Therefore, the wall thickness of this part is also larger. The edges and corners are the parts where the parison is inflated last, and the wall thickness is smaller. Therefore, the edge of the Plastic Pump and the corner should be rounded.
Third, the printed surface of Plastic Pumps is the most concentrated part of consumers' attention. The printing surface should be flat and continuous; if the Plastic Pump contains handles, grooves, ribs, etc., the design should be careful not to cause inconvenience to the printing operation. Oval-shaped Plastic Pumps have higher rigidity and higher manufacturing costs for molds. Therefore, in order to ensure the rigidity of the Plastic Pump, besides selecting a material with high rigidity, the shape of the Plastic Pump must be designed to enhance the rigidity and load bearing strength of the Plastic Pump.
