Metal powder injection molding machines and other equipment are constantly innovation and development

With development of product and forming process, forming equipment is also in constant innovation and development, focus on the development of modern injection molding machine is to control, in order to improve the level and degree of automation of the machine, and machine optimization design and processing technology improvement and meet the requirements of injection molding machine quality and saving energy. The development trend of modern injection molding machine is summed up as follows.

(1)功能专门化和价格低廉化在生产实践中,由于制品形状和塑料品种的不同,常常对注射机有一些特殊要求。例如,从制品方面来讲,有的有嵌件,有的无嵌件,有的是单色,有的是双色;从塑料品种来说,有的是热塑性塑料,有的是热固性塑料。因此,开发适合用户要求的特殊和专用注射机,具有性能价格比高、技术密集和结构简化等特征。例如,气体辅助注射设备、可熔芯注射设备、磁石与金属粉末注射机等。


(1) functional specialization and low price in the production practice, the product shape and plastic varieties, often have some special requirements for injection machine. For example, from the product side, there are some inserts, some without insert, there is some monochrome, two-color; from plastic varieties, some thermoplastics, some thermosetting plastics. Therefore, special and special injection machine suitable for the development of user requirements, with a higher ratio of performance to price, technology intensive and simplified structure characteristics. For example, gas assisted injection equipment, fusible core injection device, magnet and metal powder injection machine etc..
(2)高速、高效和精密化开闭模的速度快,模具的开闭速度从20—30mm/min,增加到40—50mm/min,有的甚至高达60mm/min。注射速度快,从100mm/s提高到450mm/s,对于中小型注射机注射速度达600mm/s的已不算罕见,有的可达900mm/s

(2) high speed and high efficiency and precision of the die opening and closing speed, mold opening and closing speed from 20 30mm/min increased to 40 50mm/min, some even as high as 60mm/min. The injection speed is increased from 100mm/s to 450mm/s, for small and medium sized injection speed injection machine of 600mm/s is not rare, some up to 900mm/s.
以中小型注射机为主,同时发展大型和超大型甚至巨型和微型注射机。锁模力达40MN50MN、甚至更大的大型注射机已经问世。原西德制造的锁模刀达50MN的注射机,注射量24.5kg,注射压力为140—370MPa。日本名机制作所制造的大型注射机,锁模力120MN。目前,普通、精密和超精密注射机的成型精度已经达到0.02—0.05mm0.01—0.02mm和小于0.001mm

In the small injection machine, at the same time, the development of large and super large or giant and micro injection machine. 40MN, 50MN, locking lidamycin and even large injection machine has come out more. The injection machine made by Germany locking knife up 50MN, 24.5kg injection volume, injection pressure of 140 - 370MPa. Large injection machines in Japan were produced by machine manufacturing, clamping force 120MN. At present, ordinary, precision and ultra precision injection molding machine precision has reached 0.02 0.05mm, 0.01 0.02mm and less than 0.001mm.
(3)自动化自动化生产是保证制品质量、提高生产率、降低劳动强度、改善劳动条件、充分发挥设备利用率、降低成本的重要途径。目前,采用许多新型控制装置,如可编制程序控制器(PLC)取代传统的继电器。编程器控制。工作可靠,程序可以灵活修改。微型计算机已用于注射机的过程控制和工艺参数的控制,这种新的控制方法对于成型精密制品特别重要,它能够自动调整成型条件,保证制品的尺寸和质量。对于生产一般制品的机器,其生产过程从加料到取出制品的检验包装也都是自动进行的。机器的安全由安全装置来保证,不但可以自动化,而且可集中管理,实现无人操作。

(3) automation production is to ensure product quality, improve productivity, reduce labor intensity, improve working conditions, make full use of the equipment utilization rate, reduce the cost of an important way. At present, with many new control devices, such as programmable controller (PLC) to replace the traditional relay. Programmer control. Reliable work, can easily modify the program. Microcomputers have been used for injection machine process control and process parameter control, this new control method for precision molding products is particularly important, it can automatically adjust the molding conditions to ensure the size and quality of the products. For the production of general machine products, the production process from feeding to remove the product inspection and packaging are done automatically. To ensure the safety of the machine by a security device, not only can be automated, and centralized management, realize unmanned operation.
(4)其他机械结构设计采用先进的方法、构思及手段,合模方式以肘杆和直压式为主,改进合模机构,形成标准化系列;主机外观及形状优化设计,降噪,注射机配套设备的标准化、系列化以及注射机的模块化,发展环保型注射机等已引起注射机生产厂家的重视。


(4) other mechanical structure design using advanced methods and ideas and means, clamping way to toggle rod and direct pressure, improved clamping mechanism to form a series of standardized; host appearance and shape optimization design, noise reduction, the modularity of the injection machine and ancillary equipment standardization, serialization and injection machine, development of environment-friendly type injection machine and other has caused the attention of the injection molding machine manufacturers.
