Automation is a great solution to meet workforce challenges, but to be successful, it’s critical that the robot is easy to deploy and operate on repetitive tasks that aren’t appealing to humans,” said Jim Lawton, COO at Rethink Robotics. “PMC demonstrates that automation can transform jobs in manufacturing rather than replacing them, as robots free up their human counterparts to pursue more meaningful responsibilities.” We make device components that help our military defend themselves, and make it possible to return home to their families safely.

In the PMC facility, Sawyer picks a part from the press and puts it on a computer numerical control (CNC) machine for holes to be drilled, detects when it is finished and places the part in a box. Sawyer waits until there are exactly 160 parts in the box, then pauses for an operator to come pick it up. The operator gives Sawyer a push to signal that it can continue, and the process repeats. Family molds, which allow different parts to be molded in the same cycle, can increase efficiency but require careful balancing of cavity sizes and flow paths. How your part will be used is undoubtedly one of the most important considerations for plastic injection molding design. While this may seem straightforward, there may be some important questions you have missed as part of this identification process, such as:What function(s) will your part serve? Is it a single component or part of an assemblyWhat market(s) is your part intended for?What application(s) will it be used in?Who will be handling your end product?Will the part endure continual use or periodic?Properties The injection molding machine's screw design influences material melting, mixing, and injection efficiency, requiring careful selection for specific materials.
Glass filled nylon injection molding is a practical choice for creating durable molded parts that will encounter friction and wear. The main characteristics and benefits of molding with this material compared to general purpose nylon include: Higher mechanical strength and rigiditySubstantially harder Stiffer partsMore heat resistant & a lower thermal expansion rateHigher creep and wear resistanceImproved dimensional stabilityHigh mechanical damping propertiesMore resistant to chemical exposure Flashing occurs when excess material escapes the mold cavity, typically due to insufficient clamping force or mold damage, and must be removed in post-processing. PMC is recognized in the industry for solving complex molding challenges that other plastic injection molders can’t solve. We are able to specialize in this area of expertise because of our certified in-house Master Molders. Since so few plastic injection molding companies have certified in-house Master Molders, most are not able to solve molding challenges or create complex products. Mold flow analysis helps engineers predict how molten plastic will behave during injection, optimizing the design for better part quality and faster production. Now, these plastic molders are forced to reduce the mold temperature in order to regain the lost productivity caused by long cooling cycles necessitated by higher melt temperatures. This high melt temperature to low mold temperature ratio often results in compromised part properties and an unstable part.
