Guangzhou plastic factory introduction to plastic injection molding process

Bottle blowing bottles machine is now more focus on a key, the government vigorously in promoting industrial cluster, ensure the balance of the industry, the construction of system, using the network to further improve the information sharing and exchange, cluster of upstream downstream industry balance; Bottle blowing with hot and cold on craft, equipment and through the development of The Times, more and more advanced, more efficient, at the same time, the operation of manual type developed from the past to the present full computer control, greatly reduced the difficulty and the stability of the process accuracy; In the process of bottle blowing pay particular attention to the temperature and pressure are: film inside, blowing, temperature difference and heat, etc. ; These are to be carried out according to the different material, material determines the quality of blow out, and the stability of the plastic bottles at the same time, according to the requirement of the blow molding plastic bottles are very harsh, and even hard to blow out qualified bottle; And more careful to the requirement of cosmetic plastic bottle, manufacturers need to consider the recycling and space, reduce waste, and for market shocks everyone to develop new market, can turn to some processing such as low labor market to expand abroad; I believe that in the current form, bottle blowing manufacturer will do better, we also want to consider injection blow molding is in the production of plastic bottles two-step process. The first step will be for plastics injection molding in a bottom type hollow billet. When plastic injection preforming die pole around the inner core bottlenecks and parison formation. In this step, the parison which can adjust the temperature status. Then the parison within the core rod is transferred to blowing mold, the air core rod imports, the parison blowing into the shape of a model. Bottle molding is completed, transferred to the discharge section. Injection blow molding of the advantages of many: no scraps, size accurate, after the bottle made without secondary processing. L g. 004 inches. The bottle weight and the size of the repeatability is suitable for matching, and is easy to be connected to the filling line. Because there was a biaxially oriented effect, can make a variety of different materials and strength improve transparency. In the discharge period of bottle is controlled by a certain direction, thus can automate online adornment and filling. The operator's workload is small. Equipment using existing injection blow molding machine for the plastic bottles of profitable production, the size and shape of the bottle. Injection blow molding machine on the market can buy several, they are from a transfer to another core rod methods, including wear edge type, two ( Paragraph) Rotary, axial movable and three sections and more than three pieces of rotary. Today's three or four popular rotating machine. This type of equipment can be divided into two categories: the blow molding assembly components, the components can be installed on some industrial plastic injection molding machine; And complete sets of plastic injection blow molding equipment, equipped with the molding machine, hydraulic device, control device and other supporting components. These devices can be further divided into: vertical reciprocating screw plasticator, and with a horizontal reciprocating screw plasticator. Vertical is much simpler than the reciprocating, in equal speed and low pressure injection molding ( If necessary) Injection quantity at the same time, its components, small energy consumption, less land, less maintenance is simple. Reciprocating screw molding machine mainly developed for injection molding; Although its structure complicated than vertical, but operation reliability is better. The current molding machinery, including large standard production equipment, can be in the production of high speed or the bottle to the larger output; The improvement of the injection device to make PVC and resin containing propylene eyes more easily processing; Add section ( A) Development work is continuing. Normally, pharmaceutical and cosmetics industry is 16 central and smaller injection blow molding of plastic bottles. Specifically for the development of new materials has led injection blow molding factory into other markets. Polypropylene copolymer easy processing, good transparency, and forming fast, so it actually has replaced the cough medicine and gargle with glass bottles. Other new resin injection moulding grade PVC homopolymer and polycarbonate. The crystal transparent materials have been more easily in the vertical screw machine for processing, also equipped with the level of the plunger straight screw screw machine for processing. New streamlined manifold and improved with acrylonitrile resin and PVC resin has many chamber operation to become a reality, although these resins are heat sensitive. An 8 a chamber mould has been successfully used in PVC processing, a number of 12 a chamber mould has applied to the production of bottles containing propylene eyes resin. Eight existing several company was about to use a chamber mold production PVC bottles, it is after modification of 01 material, in order to reduce the heat sensitive. Are obvious, with larger machines, high clamping pressure and large platen area will be able to economically produce 4 liter plastic bottles. The bottleneck of precise and non scraps from such advantages will gradually compensation mould of higher costs. Due to the development of the machine ( Increase the number of) And mold design innovation, the development of the future work will focus on the resin's targeted improvements. Mold design technology has been able to make square neck and neck bottles, plastic bottles, can make the bottle on the precision of the groove, and reduce the whole bottle of wall thickness, shorten the production time. Guangzhou plastic products company 【 4008000286 】 , 10 years focused on custom plastic container manufacturer, specialized in HDPE bottle, PP bottle, PET, PS bottle, acrylic bottle and plastic bottle caps, is widely used in health care products, food, cosmetics and pharmaceutical packaging.
