Plastic Molding Company

The plastic industry is one of the earliest invested businesses after the economic reform and open policy in China. The current decade of the 21st century, the development of the plastic industry and the foreign investments in China, where has gradually introduced into new technology for plastic mold and manufacture process. They make China growing with the mature technology of plastic mold and production capability. In recent years, variety of large fairs of plastic moulds and products were held at Shanghai and Guangzhou year by year. Those fairs successful attracted world wide¨s attentions with excellent technology and low-cost plastic mold and plastic production. That is a representative proof. 
        As a result of mature plastic mold and plastic production technology, the more and more international famous manufacturer came to China and invested to set up factories. So China went by the name of the world factory. The manufacturers from all over the world are much interested in Chinese mature plastic mold and plastic production, but it is not easy to find appropriate cooperative factory for medium and small scaled overseas corporations. They must consider the problems such as the expense of the personnel¨s business trip, the difficulty of language communication and the cooperation production quality. Therefore, lots of manufactures can not make production successfully. It is also difficult to reach the quality standard or to reduce the production cost for the manufacturers that have already made the production in China. 
        As a result of the same cultural background and language between China and Taiwan, in the initial period, Chinese plastic mold technology and plastic production manufacture flow were deeply affected by Taiwan. Taiwan¨s excellent mold technology and plastic production manufacture were acknowledged by the whole world in the last century. Sincere Tech mold. is a plastic molding company which has an excellent mold engineer and sale team from Taiwan.

Injection blow molding

plastic bottle molding Medicines are the largest production and sales of medical plastic products. With the rapid development of the domestic medical industry, the domestic consumption of medicine bottles will show substantial growth. In this regard, the domestic equipment manufacturers should be as hollow as an opportunity to grasp the development trend of plastic bottles, research and development of new high-performance, high-performance bottle molding equipment, and strive to shorten with the international advanced technology and equipment gaps.

The main molding equipment

Plastic bottle blow molding equipment, according to shape in different ways, mainly divided into three types: extrusion blow molding machine, injection blow molding machine, as well as to “squeeze – la – blow” or “Note – la – blow” molding machine. Extrusion blow molding and injection blow molding machine is mainly used for production of medicinal small plastic bottles, to “squeeze – la – blow” or “Note – la – blow” molding machine is used in the production of large bottles. At present in China, Applied Extrusion blow molding and injection blow molding machine manufacturing enterprises of plastic bottles up to.

Extrusion blow molding machine

Extrusion blow molding machinery (including the blow mold) and a lower cost, such as forming the same product, blow molding machinery, injection molding machines cost about 1 / 3 or 1 / 2. At the same time, production costs are also low. As the parison is at a relatively low pressure through the extrusion die molding and low pressure (mostly 0.2 ~ 1.0MPa) under Inflation, and therefore less residual stress in the product, and the resistance to tensile, impact, bending and the environment high performance for various contingencies, with good use of the performance. As the blow mold cavity block only by composition, so by simply adjusting the nose or the extrusion die exit gap conditions, the body can change the bottle wall thickness. In addition, because blow mold can be set to slide at the end of the module, so the bottom of the bottle-shaped body of a larger design flexibility. Extrusion blow molding the shape can be complex, irregular and the overall style of the product, and therefore more suitable for forming HDPE, PP raw materials for hard plastic bottle.

Injection Blow Molding Machine

Injection blow molding machine mainly used for processing of HDPE, PP raw materials for medicine bottles. Injection blow molding equipment, using a small plastic bottle was generally welcomed by pharmaceutical companies. As the injection blow molding of bottles in the molding process, the device can be injection nozzle bottle of injection molding, thus ensuring the accuracy of bottle; followed by a bottle blow molding machine configured mandrel body, the guarantee of the plastic bottle body shape dimensional accuracy.

Injection blow molding can be used a medicine bottle-step two-station or 3-station injection blow molding machine processing. As the two-station injection blow molding machine the lack of a dedicated off bottles and cooling stations, it is difficult to achieve fully automatic counting packaging, resulting in production efficiency was less than 3-position. Thus, in actual production use more of a three-station machine. The aircraft’s three stations to 120 ° angle into the distribution of an equilateral triangle, the first station for the injection molding station, the second station for the blow molding station, the third station for the off bottles and cooling stations. Three-station can be run simultaneously, producing high efficiency, short cycle can be connected with the conveyor automatic counting packaging, truly the whole process of production of pharmaceutical plastic bottle with the staff of the “no contact” order to ensure product cleanliness. Injection blow molding machine could not be forming the shape of complex products, and the shape of the bottle most of the smaller volume (usually 10 ~ 300ml). However, injection blow molding bottle bottle flatness high sidewall thickness uniformity, in particular, between the bottle and the bottle has good sealing performance can reach to prevent the plastic bottle of medicine and external gases of volatile gases to the bottle penetration performance requirements, which makes this bottle in full compliance with the special requirements of pharmaceutical packaging. State Drug Supervisory Authority as early as in the “Ninth Five Year Plan” period on the proposed use of injection blow molding method of producing high-quality plastic bottles. At present, China imported from abroad medicine bottle injection blow molding production lines up to more than 40, with a total production capacity of about 700 million / year.

“Note – la – blow” molding machine

“Note – la – blowing” PET, PP bottle (for filling liquid medicines) machine is divided into two kinds of one-step and two-step models. One-step model is the parison injection, heating parison, the tensile parison and blow molding processes such as product ejection device in the same row for the efficient equipment. According to molding processes, one-step model is divided into three stations (Aoki of Japan, represented by solid machine) and 4-position (in Japan’s precision machinery as the representative) two kinds of machines. The main difference between the two is: “3-station” refers to the injection with the heated parison parison in a process completed, “4-station” refers to injection with the heated parison parison in the two processes to complete. One-step model does not cause secondary pollution products, and a good product identity. Despite higher prices, but to reach the high cleanliness requirements bottles in recent years, the domestic pharmaceutical companies more inclined to use the one-step “Note – la – blow” bottle molding machine. To this end, some equipment manufacturers in the domestic absorption of foreign advanced technology and intensify the development on the basis of foreign equipment could be replaced by one-step models, and have achieved some results.

Two-step model refers to the injection and stretch blow molding process by an independent two machines separately. The first step: from a common injection molding machine injection molding tube, head tube of the bottle part (bottle, screw) had completed its forming; the second step: The tube on the honeycomb heater or automatic cycle of heating on the heat conveyor thermostat, and then moved to the stretch blowing process using compressed air to blow molding. Than the flat bottle, seal well and fast product development, mold fees and costs, lower prices are “two-step” models of advantages, but due to injection blow molding tube and the step-wise, the product identity is poor, and easy to pass pollution, difficult to check by bacteria.

R & D direction

Plastic bottle forming machine up to other hollow plastic molding equipment, specifications of small, fast, high precision and high efficiency. The main direction of its R & D high-speed, high efficiency, energy saving, environmental protection and adaptive quality control.

All-electric one-step “Note – la – Blow” Blow Molding Machine

The recent development of a high response AC servo motor-driven dosing pumps energy-saving systems, injection molding machine has been successfully applied. Similarly, injection blow molding, “Note – la – blowing” plastic bottle molding equipment of the main system power drive can also be portable such systems. The system pressure and flow through precise closed-loop control of servo motor to achieve the energy requirements of the implementing agencies the best matching and automatic adjustment, so as to achieve energy efficiency, improve performance and reduce environmental pollution multitude of purposes.

All-electric one-step “Note – la – Blow” Blow Molding Machine for its precise location, speed, no vibration, high self-cleaning as well as the advantages of high efficiency, high-performance plastic bottle molding machine into the development of hot. The key to development of aircraft types is to achieve turntable body clamping preform molding, stretch blow molding and injection-locking mechanism simultaneously plasticizing institutions of all-electric drive. All electric molding preforms and stretch blow mold body simultaneously locking mechanism design, refer to the all-electric injection molding machine clamping. For the all-electric injection of plasticized bodies, can be completely copy all-electric injection molding machine plasticizing bodies. It can be said, with the all-electric injection molding machine mature technology, which is developing electric-step “Note – la – Blow” Blow Molding Machine is not very great difficulty.

At present the domestic market all-electric one-step “Note – la – Blow” Blow Molding Machine, with Shanghai Machinery Co., Ltd. Ace must be represented by models developed by ASB-15N/10E. The machine uses closed-loop servo system, than the original hydraulic system greatly improved the stability of control, saving up to 40% and a change of hydraulic transmission fluid oil (hydraulic system valves, piping, etc. prone to leak, the use of age is even worse than the old equipment) on the environment, product contamination.

High-speed, high-quality PET, PP preform injection gasoline-electric composite body

The performance of injection plastics sector is directly related to the quality of preforms. Reciprocating screw injection of common plastics, as before and after the plasticizing quality and inconsistent, leading to inconsistent quality preform; and also because the two can be made between injection and plasticizing the same time, reducing production efficiency. Note the use of composite plastics extrusion injection system (to be plasticized with the injection of two kinds of functions from the conventional one component is divided into two parts, namely, an independent servo motor-driven extruder screw plasticizing and hydraulic plunger independent injection, both of the Inter-Noninterference), then to stabilize the PET, PP melt axial temperature and thus to achieve consistency of quality plastics, but also greatly enhance productivity.

Improve the forming rate and yield

Improve production efficiency is the domestic pharmaceutical packaging container injection blow molding equipment, the key to development. Vinda Jiangsu Machinery Co., Ltd. successfully developed the domestic first-step three-station injection blow molding machine, has in recent years is based on 100 production lines each year the size of rapid development. Use of Ouida’s MSZ60L models, the production 30ml × 12 cavity typical of conventional plastic bottles production cycle of only 10S. Zhangjiagang Green Central degradation of complete sets of equipment Co., Ltd to absorb European NOVVAPAX, BEKUM of the technology, has developed solid particles suitable for the production of medicinal polyolefin bottles of high-performance 3 station injection blow moulding machine, the shortest production cycle up to 8s. Machine dual-link mechanical protection, turntable with the opening and closing movements synchronous operation mode, greatly shorten the cycle; use of plasticizing screw extruder, screw aspect ratio increased to meet the transparent PP, PE, PS, PC and other hollow products process needs; preform temperature uniformity, product unparalleled line; with a single beam clamping structure, convenient and quick replacement of mold; machines simple shape is conducive to purification, in line with GNP specifications. Panan triple Pharmaceutical Packaging Co., Ltd. for the production of generic pharmaceutical plastic bottles technical problems, has created a unique high-pressure gas thermostat technology. The technology uses electromagnetic speed control system to replace the inverter system, reducing the machine size, reduced power consumption, and improved use of equipment performance and product quality.

Development of high-performance mold

Although in recent years, many domestic enterprises in the “Note – la – blowing” equipment to spend more energy and money, so that equipment has been reach or approach international advanced level, but because of neglect and efficient accompanying “Note – la – blowing” mold development, and therefore can not play its due role in equipment. This is a bottleneck restricting development of the industry. For relevant domestic enterprises, in order to develop a high level of “Note – la – Blow,” Die, you must use an advanced computer-aided engineering (CAE) technology to the “Note – la – blowing” process simulation, which avoided by experience, trial and error and by way of amending the blindness brought about the end, the mold material, mold cavity ratio of the different blowing Zhang, hot runner nozzle structural design, as well as temperature control, etc. have access to the most optimal results. Multi-layer co-extruded hollow plastic bottle molding machine

Multi-layer composite bottle has to avoid the light transmission and to prevent the infiltration of gases such as C02 performance, to meet certain require special storage conditions required for bio-engineering drugs, has become a major pharmaceutical packaging market, one of the products. For example, the 3-layer co-extruded plastic bottles (the most outer layer of the PA material, the middle layer of PET material, the inner layer of PC material), with good transparency and tightness can be isolated from moisture and oxygen, not only for routine blood products, such as human serum albumin and protein, collagen fibers and other products directly to packaging, but also can be used as a variety of bio-engineering drugs, such as interferon, monoclonal antibody drugs, a variety of packaging materials.

Multi-layer co-extrusion Blow molding machine bottle blow molding machine and other than the greatly increased complexity, especially in the nose design. Current research and development for the aircraft types, the main focus on the following three points: (1) to study the use of a certain range of co-extrusion head to meet the needs of different materials, different layers, and head diameter and other requirements. The nose is a multi-layer co-extruded hollow plastic molding machines of the “heart”, its performance should reach: control at every level to achieve the best condition to achieve the perfect circle and lateral material distribution; can not influence the distribution of the processed material change a wide range of plastic raw materials. Spiral mandrel composite systems are highly adaptable, multi-layer co-extruded nose should be the priority to the use of the system. (2) research portfolio of packaging systems, which can be customized according to different materials which might allow the number of combinations of nose. (3) research-based mechanical procedures in order to determine the number of molding stations, the production speed and size of product design platform.


Medicine bottles are the largest production and sales of medical plastic products, but also a rapid growth of large medical plastic products. The product is inseparable from the production of high-performance, high-performance hollow molding equipment (including mold). As the domestic Blow Molding Equipment, compared with foreign equipment, there is not a small gap, therefore, the domestic hollow plastic molding equipment manufacturers can only grasp the development trend of the bottle, research and development of new plastic bottle molding equipment, in order to gradually narrow the gap with foreign manufacturers , and in the market with rival.
