The principle of the bottle blowing machine The blowing process of the bottle blowing machine is divided into two parts. 1. Warm-up An infrared high-temperature lamp irradiates the preform to heat and soften the preform. To maintain the shape of the bottle mouth, the preform mouth does not need to be heated, so a particular

The density, hardness, and gloss of the plastic can be reduced or increased by appropriate methods to reduce or increase the plastic’s initial relative density, increase the hardness or increase the flexibility, and change the gloss to meet the needs of different applications. 1. How to reduce the density of plastic? Reducing plastic density refers

The extruder is an essential piece of equipment for plastic molding processing and pelletizing. The extruder’s everyday use can give full play to the machine’s efficiency and maintain an excellent working condition. It must carefully keep unremittingly to extend the service life of the appliance. The extruder’s primary failure is abnormal noise and abnormal vibration

During the pipe extrusion process, gas needs to vent from the melt. If these gases cannot discharge in time, defects such as pores, bubbles, and surface dullness may appear on the surface or inside the pipe products, seriously affecting the physical and mechanical properties, chemical properties, and electrical properties pipe. There are 1 to 2

A spinning machine is a machine that makes a fiber-forming polymer solution or melts from filaments. According to different fiber spinning methods, spinning machines are divided into three types: wet spinning machine, melt spinning machine, and dry spinning machine. Wet spinning machine Suitable for spinning viscose fiber, acrylic fiber, nylon, etc. The main feature is

In the plastic pipe production line, the operator’s unskilled technology and the machine operation will cause the plastic pipe to appear rough on the outer surface, jitter ring inside, uneven wall thickness, insufficient roundness and so on. Therefore, timely adjustment of plastic pipes’ production process and troubleshooting of the plastic pipe production line can improve

PE breathable membrane is a new type of waterproof polymer material. From the manufacturing process, the technical requirements are much higher than those of general waterproof materials. Simultaneously, from the quality point of view, the breathable membrane also has the functionality that other waterproof materials do not have features. PE breathable film is a new

The production process of meltblown non-woven fabrics is to use high-speed hot air to draw the thin stream of polymer melt extruded from the orifice of the die, thereby forming ultra-fine fibers and condensing on the net curtain or roller, and relying on Bonds itself to become a non-woven fabric. Comparison of meltblown fiber and

Tubing, such as PVC pipes, can be fabricated using virtually identical as used in blown film extrusion dies. Favorable pressure might be put on the interior cavities throughout the snare, or unwanted pressure might be put on the surface diameter by means of a vacuum sizer to make sure proper closing measurements. Added lumens or

Stone paper can be really just actually a form of solid and long-lasting paperlike substance generated by calcium-carbonate ensured with little bit of resin high-density HDPE. Rock paper comes with an density assortment. It can be recycled with amount 2 alloys or remade into nutrient paper and also isn’t biodegradable although can be photo-degradable below

Extrusion can be a manufacturing approach by which vinyl is then melted and shaped into a profile. Extrusion delivers things like weather-stripping, tubing, fencing, deck railings, window frames pictures and sheeting coatings, and cable insulating material. The following procedure commences by consuming plastic stuff (legumes, granules, powders or sprays ) out of the hopper to
