New type of injection machine

Engel introduced two newly developed multi-cavity injection machines. The results of its latest development of "Watermeh" water injection technology have been demonstrated in multi-point injection and multi-cavity molds. At this exhibition. The process will be used to create a removable five-piece folding box in which four parts are hollowed out by each water injection molding member. Although the core parts of the different parts are different, all four parts are supplied with molten material by a “Watermeh” device. The company also demonstrated that "X-melting process melt is pre-pressed at the front of the screw. Then inject into the mold at an extremely fast speed. This process of expansion can now be used in multi-cavity molds. The process can be used in percent one second of the time to fill a small thin-walled member. a hot runner mold cavity 4 using this process can be produced in a cell casing 5 seconds. the member of only 0.15 mm thickness and 30 mm long flow denote any company Other processes cannot do this.

This process can be demonstrated using Mold-Masters' special hot runner gate system. The molten material is compressed in the branch flow tube and then closes the nozzle gate so that the screw is completely isolated from the mold filling process. It is also necessary to have a separate plate to control the 4 gates to achieve simultaneous filling of the "X-melt" process.

Engel developed a new injection-compression module for the "Optimeh" process for producing ultra-high-accuracy optical components. The new module is mounted on the moving surface of the mold and works in conjunction with a hydraulic cylinder and closed-loop control system to produce a lens with a “moth-eye” microstructure on the surface that eliminates the use of non-reflective coatings.

Battenfeld exhibited a total of 231 tons and 300 tons of two new models in its full hydraulic HM series injection molding machines, and a range of equipment from 27.5 to 4400 tons was produced. The 231-ton model is equipped with the new Unirob R10S robot. Servo drives are installed on the shafts of the main components.

Demag improved several new features in the Extra series of universal injection machines. Includes automatic screw identification, a "friendly operation ejection function, and an ultrasonic stroke measuring system on the injection device. The ejector can be moved while the mold is open. In addition, the mold clamping pressures have been increased in the 3 models: "Extra 120" has been increased from 121 tons to l32 tons of "Extra 130" from 137.5 tons to 143 tons "Extra 160 increased from 165 tons to 176 tons.

Boy Company exhibited the automatic in-mold labeling technology of the 35M vertical injection molding machine.

2. Wilmington / Wilmington Machinery Corporation of the United States introduced two kinds of injection machines for processing structural foams. Among them, Lumina 16o0h model adopts multi-nozzle gas-assisted injection molding structural parts with a clamping force of 355 tons. Use single or dual accumulator systems. Injection volume of 25.1 pounds. And up to 64 nozzles can be set.

The other model is Lumina LP injection machine. Designed for processing structural foams, gas-assisted injection or low-pressure processing for the production of large-scale, wall-thickness parts. Molding cycle is more than 1 minute. This two-step extrusion/injection system maximizes throughput. The main branch flow path is provided with an extension block to guide the molten material. Its injection volume is between 150 pounds and 200 pounds.

Wittmann exhibited four new robots. The W710 model is an electric/pneumatic model. The effective part removal load is 11 pounds. It can be matched with a 250-ton injection machine with a fixed stroke and a vertical shaft to reduce vibration. The W711 CS3 model was developed based on the W710. There is a full servo drive system. The effective payload of the full servo W72l CS3 is 22 pounds. Can match 400 tons injection machine. The W753 model is used to match large injection machines. Its effective parts take out loads up to 165 pounds.

Spirex introduced the "Power-Purge" system. This is a system that can clean the screw, barrel and check valve without disassembling the injection device. New patent for valve design and combination cleaning.
