With our specialist Da/Pro Rubber for the manufacturing of high quality, tight tolerance rubber and plastic components we can offer medical grade materials and processes tailored to our customers' specifications.
Cadence offers a variety of plastics manufacturing capabilities and solutions specializing on PEEK Machining.
Da/Pro Rubber, Inc. offers compression moulding of rubber compounds. Compression moulding consists of a top and bottom plate mould that is machined to a custom configuration. An elastomer preform is added between the plates and the plates are compressed under heat and pressure for a specific amount of time. The Da/Pro process monitors variables closely and adjusts to compensate for variable differences during each cycle. After the elastomer is cured properly, the mould is opened, the part is removed; the mould cleaned and the cycle repeated.
Da/Pro Rubber, Inc. offers transfer moulding of rubber compounds. Transfer moulding consists of a mould cavity similar to a compression mould. In addition, the mould contains a transfer pot and a ram, where the rubber material is placed before compression. The mould cavity contains transfer holes, which connect to the transfer pot through sprues. During moulding, the ram is compressed and compounded rubber material flows through the sprues into the mould cavity configuration. Similar to compression moulding, the Da/Pro process monitors all variables and compensates for differences during each cycle. After the elastomer is cured properly, the mould cavity is opened, the part is removed, the sprue is removed, the transfer pot and mould cavity is cleaned, and the cycle is repeated.
Liquid Injection Moulding
Da/Pro Rubber, Inc. offers liquid silicone rubber (LSR) injection moulding. This type of moulding is also called liquid injection moulding (LIM). LIM is similar to transfer moulding, but the rubber material is supplied on a continuous basis through an injection nozzle. The liquid rubber is mixed in line with the cutting agents and is injected into the mould cavity. Under heat and pressure, the rubber cures. The part is then ejected from the cavity and the moulding. The tooling for this process is more precision than compression due to the low viscosity of the liquid silicone.
Da/Pro Rubber offers plastic injection moulding services. This is a manufacturing process used for making components from thermoplastic and TPE materials. The plastic material is injected at high pressure into a mould made from the inverse of the desired shape. Unlike thermoset materials such as silicone, the plastic bonds are formed as the material cools. Once the part is cooled, a mould release removes the parts.
Over Moulding / Insert Moulding
Consistent rubber bonded to metal insert and rubber-to-plastic parts are easily produced using the Da/Pro Process for overmoulding. Unitized conductive elastomer / substrate products are moulded to meet stringent customer design requirements and quality demands. The elastomers are attached to the insert substrate by mechanical and/or chemical bonds. In chemical bonding, the elastomer is vulcanized and rubber bonded directly to the metal insert or plastic substrate during the moulding process.
