Cast Urethane Parts Robots – Polyurethane Robotic Parts!
Cast urethane parts for robots often times are produced within a few weeks from a simple sketch or print. Plan Tech’s design team will work with your robotics engineers on the final details to make an idea become working functional cast urethane parts for robots in no time. Robots have already revitalized machine shops and assembly lines around the world and are making their way into supermarkets, shopping centers and retail. Plan Tech has a full in-house machine shop equipped with the latest technology including a 4 x 8 Flow Waterjet. Custom cores or urethane wheels for robots are no problem for us! Tight tolerances or prototype polyurethane wheels are also just one of the many of the cast urethane parts for robots that we can offer. On average urethane will outperform rubber 3 to 1 making urethane an ideal choice for polyurethane parts for robots. We can also add additives that will increase abrasion resistance and add lubricity to keep products from sticking. An Anti-static additive is also common to reduce any static build up from sliding.
Open cast molding is the simplest and most common molding method for thermoset polyurethanes. Advantages: Since pressures and temperatures in the molding process are relatively low (ambient pressure and temps below 250F), the molds are more cost effective and can be made from a variety of materials including polyurethane. Open cast molding urethane parts is good for parts with relatively open tolerances on one surface. If tolerances are tighter for urethane robot wheels, a secondary finishing operation is an option.
In transfer or liquid injection, pressure is used to force the liquid polyurethane out of a reservoir and into the mold. Materials are generally injected at the bottom of the part and vented at the top for the prevention of air entrapment. Advantages: Makes use of fairly low-cost molds and can achieve thin cross-sections. Parts will have a sprue and an open surface for venting air which will require a finishing operation. The part is split on a parting line, the halves are filled and the material is allowed to gel. The mold is then closed and placed into a compression press. Advantages: Compression molding yields a finished part with detail on all sides. Molds can be more expensive than those used in open casting or transfer, but parts can be quite detailed and elaborate.
