Custom precision ground ejector sleeves and bushings. 714-540-2846 or fax at 714-540-6158.
Matthews Gauge acquired the manufacturing process and services from CPS Manufacturing, Inc. in the summer of 2003. With the added manufacturing process and capacity, thin wall ejector sleeves and other precision mold tooling are now available to better serve the molding industry in the USA. Along with the custom core pins, custom ejector sleeves have been added to provide a single source for the hard to find molding components.
We can be reached daily Pacific Standard time 6:00AM to 4:30PM Monday through Friday.

Ground from heat treated and tempered tool steels to your specifications. Our products are made from quality tool steels, M-2, S-7, A-2, A-10 and other tool steels and are hardened throughout entire cross section of part. Extra long ID bearing surfaces inside ejector sleeve, custom sleeves and stripper sleeves as required for guiding long ejection stroke without "falling-off" your core pin. Full bearing contact between stripper sleeve to core pin during mold ejection cycle will help prevent damage to core pin as the mold returns to the closed position.
We can also remove large relief hole that is present in most standard sleeves. Honing the relief hole will increase wall thickness, at head area and increase the part strength. Honing only enough material to clear the core pin. Honed relief also removes ID scouring from drilling process that produces fracture lines that may cause early failure at head / body only for thin wall sleeves.
For molds that require water cooled core pins, the relief hole can be increase in size to suit the custom core requirements.
We provide a quality product. All components are "Made in America". Core pins for pen molds and pipette molds require "Cooling Cores", core pins with blind hole(s) drilled in the center for coolant with or without O-ring pockets. Custom core pins with matching sleeves honed to slip fit. Honed .0002 over the core pin diameter, is the size we hold for molded material such as nylon.
Produced from US made tool steels. Typical steels used are A-2, A-10, D-2, H-13, M-2, S-7, O-6, 440-C, 420, *UDDEHOLM STAVAX 420™ stainless steel.
*Stavax is a good choice where a high luster molding surface is required. Heat treated with certification as required.
Specializing in thin walled sleeves down to .007 is possible with overall lengths of 4.00 inches (.2500ID x .2650 OD x 4.500 long)
Precision tooling for plastic and die casting
