• Injection Molding Machine Builders
  Our sensing technology is routinely used on 4 axes of plastic injection molding machines: injector screw positioning, carriage positioning, ejector positioning, and mold closure. Superior ruggedness, reliability and performance means Temposonics sensors provide the best value for this application...
• Better Injection Molding Through Bubbles
  into the barrel of an injection-molding machine. There, a specially designed screw mixes and maintains the SCF in solution within the molten polymer. A shut-off nozzle holds pressure on the mixed melt to keep the SCF in its intermediate state. When the melt is injected through the gate and into the mold...
• Load-Frame Monitoring for Injection Molding Machines
  . for a second sensor. The injector carriage and injector screw are. while reducing the amount of costly mechanical and electrical. monitored by a single sensor on the other end of the injection. hardware on its machines. By using a high resolution Temposonics. molding machine, thus reducing the normal four...
• Isotropic Forming of Porous Structures via Metal Injection Molding
  components that is experiencing. commercial acceptance [1]. In this process, a metal powder is mixed with an organic binder to. produce a mixture, or feedstock, that has a sufficiently low viscosity to be molded using a high-. 3. pressure screw injection-molding machine [2, 3]. Since molded components...
• Molding a better plastic nut
  depending on how they are manufactured. The most common processes are machining from bar or sheet stock and injection molding from compounded resins. Injection molding is the most versatile. It inherently allows more design freedom and can accurately produce profiles not possible or too expensive...
• Medical Device Link . Injection Molding With Liquid Silicone Rubbers: Using Process Design To Maximize Results
  affects the processability of the LSR. It is important to have a positive shutoff valve at the point where the mixed material is introduced into the injection molder. This is particularly true if the molding press will ever be temporarily unattended, since the valve prevents the injection screw...
• Innovative High Strength Glass Microspheres for Extruded and Injection Molded Parts (.pdf)
  High strength, low density glass microspheres (3MTM Glass Bubbles) have been developed and commercialized for use in extrusion and injection molding processes. The new and innovative 3MTM Performance Additives iM30K are low in density, and can survive extremely high compressive forces, providing...
• Injecting more "mettle" into P/M designs

• From mini to maxi
  Maxima IMMs sport twin injection units, each with 24:1 length/diameter screw, 854-oz shot capacity enabling processing of up to 3000 lb/hr of PE, and 24-kpsi pressure. Software in the machine is preconfigured for coinjection molding. Maxima IMMs feature extended-clamp opening stroke and daylight...
• A breakthrough for in-mold assembly
  with a rubber nipple and screw-on cap. An 8+8 Spin Stack mold produces medical components using a two shot injection molding machine. The Spin Stack Technology reduced assembly time by 30 % and improved overall part quality. An in-mold painting process puts a scratchresistant coating on plastic parts...
