CoreTech Systems (CTS) offers plastic molding components manufacturing using our proprietary Metal Core Technology (MCT). When companies seek expertise in molding plastic components, CoreTech's Metal Core Technology offers them a proven production process that produces high quality, dimensionally accurate, one-piece, hollow plastic parts which have complex internal and/or external geometry. The process has found merit with numerous plastic molding processes including plastic injection molding; resin transfer molding; filament winding; hand lay-up; as well as many other methods.

CoreTech provides prototyping and full injection plastic molding production services of composite parts made from a wide range of thermoset and thermoplastic resins. These materials are loaded with various glass, graphite and other fillers. CTS can also supply clients with metal cores alone, permitting in-house plastic over-molding.

CoreTech's proprietary MCT process offers numerous benefits over other production methods

CoreTech's MCT process provides a competitive edge in most applications by simplifying the plastic parts manufacturing process, and yielding economic benefit over other production methods including gas assist, foam cores, adhesive bonding, soluble polymers, and welding.

The MCT "lost-core" molding process has found merit in applications where:

• Consolidation of multi-piece plastic components into one part;
• Integration of multiple plastic parts into one part; and/or, rotation from metal or other materials, into one plastic component.

The MCT process permits increased flexibility in the design of hollow complex shaped parts, often permitting manufacture, including injection molding, of parts once considered too complex for a single-piece molding or otherwise impossible to manufacture by any other method. Since its introduction in the mid '70's the MCT process has proven beneficial in the manufacture of numerous plastic parts in many industries, including automotive (air intake manifolds, water pumps, thermostat housings, steering reservoirs, air ducts); aerospace/aircraft (struts, fans, blades, thrust reverses, housings); recreational goods (bicycle wheels/frames; paddles/oars; tennis/other racquets); plumbing (faucets) and pumps (industrial impellers and fans), and other general industries.

CoreTech's engineering staff provides the part design expertise you need

CoreTech's engineering staff provides support to achieve optimum plastic part design, with the highest consideration to meet performance and manufacturability requirements. CTS will conduct a Preliminary Engineering Evaluation of any plastic component to determine the viability of using the MCT process to produce the part. Following this, a more formal Application Analysis Study (AAS) can be commissioned. This study generates valuable information from which the client can make a "go"/"no-go" decision to proceed with the development of the plastic part. The AAS includes a complete engineering analysis of the plastic part, costs to complete prototyping of the part; projections for in-house production equipment costs; and for those not seeking to manufacture the part themselves, an estimated "piece price" for the supply of the part utilizing CTS's sub-contracted production facility.

The MCT "lost-core" process involves the use of a low melting temperature metal core, which is then loaded into a plastic molded tool, over molded and then melted-out after the part is formed. Standard plastic molding practices are utilized. Most resins can be accommodated.

Environmentally friendly, the MCT process recovers 99.9% of the metal core alloy and reuses it repeatedly to make new metal cores. A wide temperature range of proprietary metal alloys are available to serve in most resin over-molding applications. High quality smooth core surface and tight, repeatable dimensional accuracy supports molding of parts to the strictest of dimensional tolerances, normally 0.0015" per dimension. Control of wall thickness is consistently met.

Lower your component manufacturing costs with CoreTech's proprietary MCT process

CoreTech's process has helped numerous clients achieve lower plastic component manufacturing costs derived from materials savings, process simplicity and reduction in secondary/finishing operations.
