Since the second plate injection molding machines imported in 1970s, It developed about 20 years. Two plate injection molding machine is compact and energy efficient, and it`s widely used in different industries. Two plate clamping mechanism has become the mainstream clamping construction for medium and large injection molding machines. What is the Top Plastic Injection Molding Machines Trends for 2016?
Many Chinese enterprises focus on the development of two-plate injection molding machines in recent years. What is the highlights and future trends?
Trend 1: Bigger tonnage
Two-plate injection molding machine was developed on machines that tonnage is over 1000 ton (clamping force is over 10000KN) and in order to save the plant area. Now two-plate injection molding machines is became more and more common due it can save much rooms. Fast mold close is the biggest advantage of the traditional three-plate toggle injection molding machines, but needs larger plant areas. With years of development, the two platen machine`s is getting much fast than before and it`s faster the three platen ones. And it`s precision is better.
Trend 2: Hybrid Power ( hydraulic + electric power)
Besides bigger tonnage, electro-hydraulic technology is another development trend of the two-platen injection molding machines. Electro-hydraulic technology combined the advantages of electric and hydraulic: high precision, fast, energy-saving, environmentally friendly, reliable and durable.
For example, use electric motor for plasticizing and injection system while clamping unit and other process is driven by hydraulic. This is a common application for the injection molding machines used to product automotive parts.
Trend 3: functional and intelligent equipment, data sharing
Another trend on the two-platen injection molding machine is became functional and intelligent. Functional diversification like pitman style clamping, mold tiny open, tiny foam function integrated. Intelligent designed like individual set up a automatic production line or even build a central feeding and controlling system. These designs can improve the production efficiency a lot.
Two-platen injection molding machines with take applications like install 6-axis robot, use post-processing, pressure injection process, stack molds and Tandem molds technologies.
Injection molding machines and other auxiliary equipment (hot runner, magnetic templates, mold temperature, neutron independent control, robots, retooling platform,etc) integrated with PC network communications and real-time data sharing is another point of the trends.
Trend 4: applications-oriented development multi-material injection
In some aspects of supporting an automobile industry, the injection molding machine must meet the requirement of car`s lightweight and comfortable experience. And develop some new dedicated model like M-type multi-material injection mechanisms machines.
There is no toggle and tail platen for the two-platen molding machine. This makes it much more convenience to add a horizontal injection unit to achieve M-type multi-material injection. The new design works together with a horizontal rotary mold can increase the efficiency twice to produce multi-color products. But the clamplping force is reduced to a half.
