  • What is the Glass Transition Temperature, Tg?

    The glass transition temperature is more important in plastics applications than is the melting point because it tells us a lot about how the polymer behaves under ambient conditions. details>>
  • What Causes Flash in Plastic Injection Molding?

    Flashing on a part can occur for several reasons, from variations in the process to material to tooling trouble. It can appear on the parts edge along the parting line of the mold. Flash during the injection molding of a part can occur during the filling or the pack/hold stage. details>>
  • Friction Welding of Plastics

    The welding process has found many applications ranging from automotive, for example air intake manifolds and expansion tanks, through to domestic appliance components such as a cistern ball float. details>>
  • Hybrid 3D Printing: What You Need to Know Now

    The concept of merging additive and subtraction techniques in one machine, a so-called hybrid 3D printer, has been around since the 1990s. Slow commercialization of the technology left hybrid 3D printers mostly off the radar of design engineers. details>>
  • Deflection Temperature Testing of Plastics for Service Temperature Determination

    The deflection temperature is a measure of a polymer's ability to bear a given load at elevated temperatures. The value obtained for a specific polymer grade will depend on the base resin and the presence of reinforcing agents. Test results are a useful measure of relative service temperature for a polymer when used in load-bearing parts. details>>
  • Benefits of Gas Assisted Injection Molding

    Enhanced quality, reduced cycle times and component weight reductions can be achieved by the process. Most thermoplastics can benefit from the use of gas assisted moulding including ABS, Polypropylene (PP), HIPS, Polycarbonate (PC), PPC and Nylon (including glass filled grades). details>>
  • Reason Why Plastic Injection Molded Parts Delaminate

    Delamination can be defined as a separation of the layers within a molded part. It can also appear as fish-scaling. details>>
  • Top 5 Purging Tips for Injection Molding

    Ultra Purge offers its excellence with its Injection Molding tips to help remove and reduce down time and scraps. These five recommendations are easy to do and require no monetary investment. details>>
  • Anti-Static and Conductive Plastics

    What is static electricity? -- electricity at rest. This electrical charge is the result of a transfer of electrons that occurs due to the sliding, rubbing, or separating of a material, which is a prime generator of electrostatic voltages. details>>
  • Joining Systems for PVDF: What to Consider

    Polyvinylidine fluoride (PVDF) is a popular choice for piping in high purity water and acid applications. Although it is widely used, proper recommendations for joining PVDF are often lacking. The most common joining systems are discussed in this article. details>>
