High Speed Side Entry IML Robot for HD420K -- SW833-S6
The HD420K is a high speed injection molding machine of the K series manufactured by NingBo Haida Plastic Machinery Co., Ltd. for the high speed production of thin-wall containers. With a clamping force of 4200kN and opening stroke up to 730mm, the HD420K is suitable for IML projects such as Yogurt cups up to 16 cavities or containers with height ≤193mm.
Enhanced twin-cylinder twin-rod injection mechanism has reduced injection return oil pressure and improved injection speed and service life, with dual linear guide double-carriage balancing seat mechanism to enhance accuracy in cylinder positioning. Precise screw has greatly improved injection precision and reduced defect rate. Optional original imported pneumatic nozzles are easy to open and close, with reliable sealing; and adopt reinforced cylinder thickness and high-power heating device to ensure plasticizing efficiency.
Use high-rigidity thick platen to reduce deformation due to mold expanding; optimized five-point toggle clamping mechanism to realize uniform load on platen, with stable and rapid movement. Apply high strength compression wear-resistant self-lubricating bearing to lock shaft and pull rod to reduce impact and to increase service life; longer platen guide mechanism to have stable platen movemnet, higher mould opening precision and convenient picking of mechanical arm; volumetric crationing dilute oil shaft made of enhanced high-quality alloy steel to greatly increase service life.
Use high-speed stock motor and hydraulic components of international famous brands to ensure high-speed and efficient operation with long service time. High response oil circuit and hydraulic valve board modular design and optimized oil circuit layout with non-damping have reduced pressure loss effectively, and improved responsiveness. Optional injection and clamping proportional reversing valves have improved positioning precision and response speed. With effective and reasonable configuration of servo system, the injection speed is more than two times of ordinary machine. Optional infrared nano heating device has further improved plasticizing quality.
Latest international distributed control system, latest hardware design, intelligent interface with EtherCAT CAN communication technology and faster CPU computing speed are specially developed for the whole motor and high speed machine. Application of all-digital communication technology has improved varous technical indexes significantly, with more accurate control on pressure and flow. Graphical display of various action and state let users know conditions of machine in a more intuitive way. Reserved internet management system and energy consumption display can realize remote real-time monitoring and maintenance diagnosis on each injection machine, as well as advanced management such as reasonably arranged production, etc.
To maximize the productivity of the HD420K, the producers of the thin-wall containers can choose the SWITEK SW8 Series of high speed side entry IML robot, which is a series of side entry IML robot for injection molding machines with clamping force from 150T~750T. With optimized control system and modular design, it's one of the fastest side entry IML robot available for the production of small and medium size containers.
