How To Choose Injection Molding Machine For Energy Saving And Environmental Protection

< p > the evaluation standard of injection molding machine mainly has several points: < /p >

The technical parameters of < p > 1. < a href= "http://cailiao.sjfzxm.com/" > injection molding machine < /a > should be advanced and reasonable.

Users can distinguish them vertically or horizontally.

The so-called "longitudinal" is that the injection molding machine main technical parameters should meet the industry standards, according to the industry standards.

The so-called "horizontal" is based on the technical parameters of similar injection molding machines both at home and abroad.

Therefore, this is a very careful and scientific work.

According to the material, shape, structure and application fields and specific occasions of injection products, according to the structure, quality, accuracy, number of cavity, type and structure, shape and size of the runner, the parameters of injection molding machine are selected according to the daily, monthly and annual production capacity and automation level of the products.

< p > 2. the stability, reliability, safety and service life of the machine.

The stability of the machine mostly depends on whether the clamping mechanism and injection system operate smoothly in different cycle periods, and the noise is not allowed to exceed the industry standard without impact.

These conditions are related to the mechanical manufacturing accuracy and assembly accuracy, and are also related to the rational design and structure of the elbow link.

The reliability and service life are mainly reflected in the rigidity of the clamping mechanism, which is related to the structure, size, material and heat treatment process of the template, tie rod, connecting rod and pin, and the structure and manufacturing technology of the driving spindle of the plastic injection system such as the barrel, screw, screw head, check ring and screw rod. These parts are the main load parts and wear parts of the injection molding machine, which directly affect the service life.

The safety of injection molding machine is very important.

When the clamping mechanism is opened and closed, the reliability of the low pressure protection system involves human-machine safety.

Modern injection molding machines require electrical, mechanical and hydraulic joint safety protection systems. This protection mainly embodies two aspects: one is the safety protection for the mould, the other is the safety protection for the human body.

Before closing the mold, when the safety door is not closed, the closing die should not be able to move; during the closing process, if the safety door is not properly closed, the template action stops or automatic die opening.

If the mould is mistakenly put into the mold when the foreign body falls into the cavity, or other foreign objects, such as vibration, etc., when the mould is closed, the mold should stop closing the mold or automatically die and alarm.

< p > another safety step of injection molding machine is to prevent the cold start of preformed screw. When the material of the screw does not reach the specified temperature and holding time, it is prohibited to start, otherwise it will alarm.

The protection device for spray nozzle of injection molding machine is necessary to prevent scalding.

< /p >

< p > 3., with high automation, complete functions and high production efficiency.

Modern injection molding machine can realize manual, semi-automatic and fully automatic operation. As long as the mold design is reasonable, automatic operation can be realized from the injection molding to the top of the product, and it can also be equipped with mechanical hand to realize the unmanned operation.

The function of core pulling, hydraulic nozzle control and fast heating channel probe function can be automatically programmed in the injection molding cycle.

The high efficiency is mainly manifested in the short molding period of each mould product under normal injection molding conditions.

This is a comprehensive performance index reflecting the mechanical, electrical and hydraulic systems of an injection molding machine. Therefore, high quality hydraulic and electronic components must be adopted, and precise manufacturing technology can be used to improve the sensitivity and repeatability of the injection molding machine system, which is a reliable guarantee for the efficient operation of the injection molding system.

< p > 4. energy saving and environmental protection are the important indicators to evaluate modern injection molding machines.

Energy saving is mainly reflected in the injection molding machine in the power driven system, heating system, cooling system to meet the normal process conditions compared with the same machine, water saving, electricity saving ability.

The theme of environmental protection should be fully considered in the design of modern injection molding machines.

Injection molding machine should prevent leakage of hydraulic oil or excessive noise, and work quietly.

In addition, the injection molding machine itself should also use more environmentally friendly materials.

< /p >

< p > 5. human-machine conversation ability and maneuverability.

Injection molding machine should make its operation and management more humanized, operate conveniently, display clearly, understandable, and be clear at a glance.

It has the functions of parameter selection, product quality control, mold data storage and automatic reproduction of various parameters. It can quickly diagnose and eliminate faults, reduce waste of materials in the shortest time and restore normal operation of the system.

< /p >

< p > 6. machine maintenance and repair should be convenient.

The installation position of various machines, such as machinery, hydraulics, electronics and electrical appliances, should be conducive to the maintenance and repair of machines. At the same time, the generalization and standardization of injection machines are also very important for users.
