  • KEYSTONE ENGINEERING COMPANY

    Since 1950 Keystone Engineering Company has maintained a proven reputation for reliable service to industry. Three manufacturing plants cover over 50,000 square feet. Thus we can ensure   prompt delivery of machined parts made from advanced composite materials and metals.  Strict documented quality control and inspection procedures ensure that all manufactured products are made from only the finest materials and to exact client specifications. All our departments are committed to high quality workmanship and service.

     

    CUSTOM MACHINE WORK AND MANUFACTURING CAPABILITIES

    Keystone maintains a broad-based, multi- disciplined manufacturing operation including special equipment for high technology products. Our total in house capabilities guarantee excellence in workmanship from prototype development through production runs.   Some of these   capabilities   include plunge    EDM,   gun drilling, 6th axis milling, composite fabrication, shot peening of metals, standard lathe.

    PLASTIC MOLDING: Automatic and semi-automatic injection and transfer molding of Epoxies, Fluorocarbon resins, Polycarbonates, Polyimides, Aromatic Polyethers, and high performance materials. High temperatures are used, with injection   pressures   up   to   42,000    PSI   and clamping force up to 100 tons.

    RUBBER MOLDING:  Conventional transfer and compression molding of Neoprene, Nitriles, Fluoroelastomers, and proprietary compounds.

    PRECISION MACHINE WORK: Keystone does virtually all machine work in house utilizing numerous modern CNC lathes and mills, which include plunge EDM, 6th and 5th axis milling. Prototype and small lot production can be done on conventional engine and turret lathes, mills, centerless and surface grinders, drill and punch presses, shears and saws.  We have seven long bed lathes with capacities up to 24 inches swing and 20 feet long work   piece.   All fixtures and molds are made in-house.

    WELDING: For critical hermetic welds that are Helium tight to 10-9cc/ sec, Keystone utilizes computer controlled   Laser and an Electron Beam. TIG and Plasma welding are used for non-critical applications.

     

    DOWNHOLE INSTRUMENTATION

    Keystone Engineering is a leader in the manufacture of downhole high strength and high temperature laminates. Our   standard Kemlox "G” material is ideal  for Mandrels and  Cover Sleeves operating from 350°F to 400°F in a downhole     environment. Where higher temperature resistance is required Keystone utilizes Kemlox HT-2 material.

    Keystone has proprietary bonding techniques for metal-fiberglass-rubber; void free resin systems, and fabric styles.  Keystone has the total in house capability for the contract manufacture of a wide variety of oilfield downhole instrument assemblies, from   a   prototype developmental stage to production runs. 

     

    Tools which incorporate our composite materials may include induction, lateral log, and resistivity types. Our material acts   as an electronic window while still providing insulation, strength and chemical resistance at 300° F plus temperatures.   Other uses may be strength members and tube liners.

     

    QUALITY CONTROL

    Keystone Engineering maintains a quality control program with complete manufacturing documentation and traceability. The program is in accordance with and exceeds MIL 9858-A for military systems requirements and is designed to achieve   ultra-reliable products.  A written schedule for calibrating gages, measuring, and test equipment is strictly followed in accordance with MIL 45562.

    ENGINEERING SERVICES

    Keystone’s has on staff a registered professional engineer with "hands-on" experience in utilizing technology and materials suitable for downhole, geophysical, aerospace, marine, and chemical use.

    MATERIALS

    Keystone offers a variety of industrial fabrics for strength reinforcement and many different binder systems. The fabric material can be comprised of E Glass, S Glass, Graphite, Ceramic, or Kevlar fills. Some of our typical binder systems use Epoxy, Polyester, and Phenolic resins. Ultra high product quality is achieved through a combination of proprietary resin   injection methods and wet wrapping techniques. Keystone Engineering has several other proprietary resin systems with heat resistances from 400°F to 450°F for downhole and industrial use.  We will be glad to discuss how our other high-temperature resin systems can serve your needs.

    RESIN SYSTEMS

    Keystone Engineering fabricates a standard epoxy laminate which approaches the maximum obtainable properties for a fiberglass reinforced material. Keystone’s   Kemlox “G” material has good strength at high temperatures, excellent thermal and electrical properties, good machinability, and outstanding chemical resistance. Where higher temperature resistance is required, Keystone has available HT-2 material. Keystone’s standard fill is E- Glass.   Keystone also incorporates other fabric fills such as Graphite, Kevlar, Ceramic, and S- Glass.

    Our standard resin systems can incorporate all of these different fills to achieve different properties.  Table 1 compares the heat resistance, density, toughness, stiffness, cost, and impact resistance of these fabric fills.
