PLASTIC INJECTION MOLDING MACHINE NPC 450
● CLAMPING UNIT
Strong rigidity of the tenplate and stable operation
○Diagonal type dual toggle mechanic mould clamping mechanism
○One-piece casting of the connecting rod before connection
○Triple mechanical, hydraulic and electrical interlocking protection
○Standard interface of the neutron device
○Auromatic centralized lubrication system
○Auromatic mould adjustment function
1. Optimized one-piece front connecting rod is wholly casted, thus to guarantee a fine rigidity and smooth movement. The main locking shaft remains static during opening and closing action, thus to reduce wearing of the die.
2. Molybdenum-contained copper sleever or a self-lubricating guide sleeves are used on the draw bar and the guide bar. By mans of its specialabrasion resistance and low friction coefficient, it dramatically increases the life service of the draw bar.
3. The moving template adopts an extended anti-skid design, which makes the machine run more smoothly and protects the mold.
4. The templates adopts T-shape slot. The rasonable T-shape slot arrangement not only makes it convenient to install moulds, but also enhances the strength of the template.
5. Below the tail board of NPC730 or above products is installed with an antiwear pad to lower the friction coefficient of the template during adjustment and make it convenient for adjustment.
6. The tie bar is analyzed by CAE, Afer professional heat treatment and centralized treatment by CNC machining, It can effectively control the precision and quality of the tie bar and improve the service life of it.
● INJECTION UNIT
