Below is a list of frequently performed post molding operations to help when discussing your next plastic injection molding project.
Assembly/Clean Room Assembly is assembling various plastic components and other components to make a sub-assembly or a complete component utilizing techniques like Ultra sonic welding, UV bonding, Air Cured bonding and Heat Staking. Assembly functions can also be performed in a clean room when bioburden and foreign particulates for all parts and completed assembly are a concern.
Packaging/Clean Room Packaging is enclosing or protecting products for distrubtion, storage or sale, this can be performed in a clean room when bioburden and foreign particulates for parts are a concern.
Heat Staking is when a plastic stud protruding from one component fits into a corresponding hole in the second component, the tip of the stud is heated to the point of softening, at which time, it gets flattened forming a head that is larger than the opening in the second component, this keeps the two parts from separating. This is a relative quick and simple process, no extra parts are required to join pieces together and plastic parts may be joined to other materials.
Ultra Sonic Welding a process for joining complex plastic injection molded parts by a solid-state weld created under pressure, there are no connective bolts, nails, soldering materials or adhesives.
UV Bonding & Air Cured Bonding - UV Bonding is the process of bonding using adhesive cured by ultra violet light. Air Cured Bonding is the process of bonding adhesive cured by air.
Pad Printing is a printing process where images are being transferred from a pad onto a plastic component.
Milling, Drilling & Tapping - Milling is the process of removing or cutting away unwanted material. Tapping is done in conjunction with drilling and consists of putting threads in a pre-drilled hole in your plastic component. Vacuum/Pressure Testing a defined vacuum is generated in a chamber to measure integrity and measure leak-proofness of plastic components. EMI shielding is performed to prevent passage of electromagnetic waves into or out of a plastic device.
Sterilization is the removal of all living organism including resistant forms such as bacterial etc, this can be done by irradiation (gamma ray or e-beam) and gaseous chemicals.
Annealing is a heat treatment that alters the microstructure of a material causing changes in properties such as strength and hardness.
