The Sub Gate is the sole gate in plastic injection mold that is automatically trimmed. Pins that eject the components are needed in this type of gate. It is commonly used by plastic manufacturers and has numerous variations like the tunnel gate or banana gate when it comes to injection molded plastic.
Plasma cutting performed by an industrial robot. Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma. Typical materials cut by this process include steel, aluminum, brass and copper though other conductive metals may be cut as well. Plasma cutting is often used in fabrication and welding shops, automotive repair and restoration, industrial construction, salvage and scrapping operations.
Plasma treatment is a surface modification technique that readily primes any surface for better acceptance of secondary manufacturing applications. Plasma is a reactive treatment process where positive and negative ions, electrons, and radicals react and collide as long as an electric potential difference exists. TriStar uses low pressure, or vacuum plasma, for more consistent and longer lasting surface treatments. With plasma treatment, you can: 1  Microscopically change surfaces for improved bonding. 2  Micro-clean to enhance the surface wetting of adhesives or over-molded elastomers.  Functionalize groups (carbonyl, hydroxyl and others) to improve surface energy.
