  • blow molding

    blow molding moulding is a specific manufacturing process by which hollow plastic parts are formed and can be joined together. it is also used for forming glass bottles or other hollow shapes. in general, there are three main types of blow molding: extrusion blow molding, injection blow molding, and injection stretch blow molding. the blow molding process begins with melting down the plastic and forming it into a parison or, in the case of injection and injection stretch blow molding, a preform.

  • poly p-phenylene oxide

    poly p-phenylene oxide or poly p-phenylene ether ppe is a high-temperature is rarely used in its pure form due to difficulties in processing. it is mainly used as blend with polystyrene, high impact styrene-butadiene copolymer or polyamide.

  • obstetrical forceps

    obstetrical forceps are an instrument that can be used to assist in the delivery of a baby as an alternative to the ventouse vacuum extraction method.

  • extrusion coating

    extrusion coating is the coating of a molten web of synthetic resin onto a substrate material. it is a versatile coating technique used for the economic application of various plastics, notably polyethylene, onto paperboard, corrugated fiberboard, paper, aluminium foils, cellulose, non-wovens, or plastic films

  • extrusion moulding

    extrusion is a manufacturing process used to make pipes, hoses, drinking sts, curtain tracks, rods, and fibre.the granules melt into a liquid which is forced through a die, forming a long 'tube like' shape.the shape of the die determines the shape of the tube. the extrusion is then cooled and forms a solid shape.

  • metal injection molding

    metal injection molding mim is a metalworking process in which finely-powdered metal is mixed with binder material to create a 'feedstock' that is then shaped and solidified using injection molding. the molding process allows high volume, complex parts to be shaped in a single step.

  • rotational molding

    rotational molding developed further and r.j. powell used this process for molding plaster of paris in the 1920s. these early methods using different materials directed the advancements in the way rotational molding is used today with plastics. plastics were introduced to the rotational molding process in the early 1950s. history equipment and tooling production process mold release agents materialsreaction injection molding

    reaction injection molding rim is similar to injection molding except thermosetting polymers are used, which requires a curing reaction to occur within the mold. common items made via rim include automotive bumpers , air spoilers , and fenders .

  • thermosetting polymer

    a thermosetting polymer, resin, or plastic, often called a thermoset, is a polymer that is irreversibly hardened by curing from a soft solid or viscous liquid prepolymer or resin. curing is induced by heat or suitable radiation and may be promoted by high pressure, or mixing with a catalyst.heat is not necessarily to be applied externally. it is often generated by the reaction of the resin .

  • compression molding

    compression molding was first developed to manufacture composite parts for metal replacement applications, compression molding is typically used to make larger flat or moderately curved parts. this method of molding is greatly used in manufacturing automotive parts such as hoods, fenders, scoops, spoilers, as well as smaller more intricate parts.

  • obstetrical forceps

    these are used when there is substantial molding, that is, temporary elongation of the fetal head as it moves through the birth canal. elliot forceps 1860 are similar to simpson forceps but with an adjustable pin in the end of the handles which can be dn out as a means of regulating the lateral pressure on the handles when the instrument is positioned for use. they are used most often .
