Injection Molding Machine Optional Points
Injection molding machine is a common plastic machinery, for the use and purchase of injection molding machine operators, we should first understand what a good injection molding machine performance, which aspects need to be assessed in order to choose a desirable injection molding machine, Here we come to understand what you want to buy injection molding machine should pay attention to.
Buy injection molding machine injection molding machine technical parameters. When users buy injection molding machine can be compared by vertical or horizontal to determine. The so-called "vertical" is the main technical parameters of injection molding machine should meet the industry standards, according to industry standards review. The so-called "horizontal" is based on the same type of injection molding machine at home and abroad compared to the technical parameters. Therefore, this is a very careful and scientific work. According to the injection molding products, materials, shape, structure and application areas and specific occasions; According to the mold structure, quality, precision, the number of cavities, the type of flow channel and its structure, shape, size; Year of production capacity automation, etc. to choose all levels of injection molding machine parameters.
Select the injection molding machine to choose from suppliers, it is best to choose the nearby service providers purchase, because the injection molding machine structure is complicated, it is inevitable that there is no problem, efficient after-sales service is the key, when purchasing do not blindly seek low prices, injection molding machine On the parts, domestic and imported prices vary widely, so you need to try to figure out what brand of manufacturers used accessories. Of course, some accessories you can not see, such as oil seals, bearings, etc., so this time the visibility of manufacturers, credibility is the key.
The choice of injection molding machine models, injection molding machine two main parameters is the amount of injection and clamping force. In order to ensure the quality of processed products, the actual weight of a mold product should be within 70% of the theoretical machine output. According to the projected area of the product calculated the required clamping force size. And pay special attention to the distance between the columns of the machine, the mold opening stroke and the minimum mold thickness is suitable for the mold.
Optional injection molding machine man-machine dialogue ability and maneuverability. Injection molding machine should make its operation and management more humane, easy to operate, the display should be clear, easy to understand, at a glance. With the parameters of choice, product quality control, mold data storage and automatic reproduction of each parameter, the fault can be quickly diagnosed and ruled out, in the shortest possible time to reduce material waste and restore the normal operation of the system.
Buy machine points of injection molding machine stability, reliability, safety and service life. The stability of the machine is manifested in the mold clamping mechanism and injection molding system in each cycle is running smoothly, without impact under the mute work, the noise shall not exceed the industry standard. These conditions are related to the manufacturing and assembling precision of the machine and are also related to the rational design of the elbow connecting rod and its structure. Reliability and service life, mainly reflected in the mold clamping system rigidity, and template, rod, connecting rod and its pin shaft structure, size and material and its heat treatment process and so on; plastic injection molding machine system such as cartridge , Screw, screw head, check ring and screw drive spindle structure and its manufacturing process, these pieces are the main force of the injection molding machine parts and wear parts, directly affect the service life. Injection molding machine safety is very important. Mold clamping mechanism in the opening and closing mode, the reliability of low-voltage protection system involves man-machine safety. Modern injection molding machine requirements must implement the electrical, mechanical, hydraulic joint safety protection system, this protection mainly reflects two aspects: First, the mold of the security protection, and the other is the personal safety protection. Before closing the mold, the mold should not move when the safety door is not closed. If the safety door is not closed to the correct position during mold closing, the mold operation will stop or the mold will be opened automatically. If you close the mold, the foreign objects such as inserts, due to vibration and other reasons into the cavity by mistake, or other foreign matter such as starting, etc., the wrong mold, the mold should stop the mold closing action, or automatically open the mold and alarm .
Another safety aspect of the injection molding machine is the pre-molding screw to prevent cold start, when the screw material does not reach the specified temperature and holding time, is prohibited to start, otherwise an alarm will occur. Injection molding machine nozzle splatter protection is necessary to prevent burns.
The point of purchase of injection molding machine to a higher degree of automation, function should be fully improved, high production efficiency. Modern injection molding machines can be manual, semi-automatic, fully automatic operation, as long as the mold design is reasonable, you can achieve from injection molding to the top of the product falling automatic operation can also be equipped with robots to achieve unmanned operation. Suction plug function, hydraulic nozzle control function and fast heating runner probe functions can be programmed into the injection molding cycle automation program, automatic cycle. High production efficiency mainly in the performance of each mold in the normal injection molding process conditions, the molding cycle is shorter. This is a reflection of an injection molding machine mechanical, electrical, hydraulic system performance indicators, therefore, must use high-quality hydraulic, electronic components, the use of sophisticated manufacturing technology to improve the injection molding machine system sensitivity and repeatability, which Is efficient injection molding system is a reliable guarantee.
The point of purchase of energy-saving injection molding machine and environmental protection is the evaluation of modern injection molding machine can not be ignored indicators. Energy saving, mainly reflecting the injection molding machine in the heating system (electromagnetic heating), power drive system (inverter, server, etc.), cooling system to meet the normal process conditions compared with similar machines, water-saving, energy-saving capacity. Modern injection molding machine design should fully consider the theme of "environmental protection". Injection molding machine should prevent the leakage of hydraulic oil or excessive noise, to work quietly. In addition, the injection molding machine itself should also use more environmentally friendly materials.
Buy machine point of injection machine maintenance, overhaul should be convenient. Various machines such as mechanical, hydraulic, electronic, electrical components should be installed in the location of the maintenance and repair of the machine, while the universal injection molding machine, the degree of standardization is also very important to the user.
