Moulding

Introduction
All vulcanising methods can cause burns. Insulate hot machine surfaces to prevent accidental contact where possible. Otherwise, warning signs and protective clothing (for lower arms as well as hands) are likely to be required.

Compression moulding
Compression moulding is the most common moulding technique used in the rubber industry. It involves pressing uncured rubber between heated moulds so that the rubber compound first fills the mould cavity before curing to produce the finished article. The presses are usually hydraulically or pneumatically powered and the moulds can be heated electrically, by steam, or by oil.
Compression moulding presses are generally vertical (the moving platen is raised or lowered in the vertical plane). The bottom platen can be up stroking or the top platen down stroking. Moulds may be fixed to both the platens, part fixed to a platen, or totally free to be drawn out of the press and loaded and unloaded on a press table. These loose moulds are usually charged (loaded) and stripped (unloaded) by hand. On fixed mould presses, mechanical devices, such as ejector pins or strippers will speed up the operation. This can reduce the need for close approach by the operator but can introduce additional trapping hazards. When thin sheets such as car mats and gaskets, are being moulded it is possible to mould several items per press cycle by using several sets of moulds. Each mould is placed between platens in a multi-daylight press - the number of daylights is the number of spaces between the platens.

Stripwound Metal Hose

Description

Stripwound Metal Hose made by helically winding a pre-formed metal strip into a fully interlocked profile. The hose gets its flexibility and suppleness from the sliding of metal components within the interlock section.

Principal Applications

The ideal hose for conveyance of truck exhaust gas and all applications requiring a very strong and flexible hose. Very efficient mechanical protection (armouring against impact, crushing, hot metal splash) of rubber hoses, electrical cables and heat insulation of technical hoses.In the smaller diameters, excellent mechanical protection of electric wires and cables, telephone hand set cables, security roller doors, thermocouplers, instrument wires and parachute rip cord housings. Also ideal as a lining for other hoses in abrasive media applications.

Standards

Manufactured to the specifications where applicable of ISO 15465 Type DOU.

Pressure Capability

Whilst this hose cannot be expected to retain gas or materials under pressure, it can generally be used for pressures up to1 bar (100 kpa) where the discharge end of the hose is open ended.

Materials of Construction and Temperature

Galvanized Steel - up to 350˚C

Stainless Steel AISI 304 - up to 750˚C

Supply Lengths - standard

5-152mm- 9, 15 metes

178-355mm- 5 metes

Smooth Bore Stripwound Metal Hose

Description

Smooth Bore Stripwound Hose is made by helically winding two pre-formed strips of metal into a double interlock hose. Through a unique manufacturing process the inner liner becomes an integral part of the hose. It covers the interlock joints to form a relatively smooth inner bore.

Materials of Construction and Temperature

Stainless Steel AISI 304 - up to 750˚C

Maximum manufacturing lengths: up to 102mm9 Metes/114 to 152mm 6 Metes/over 152mm3 Metes

Standards: Manufactured to the specifications where applicble of ISO 15465 Type DOU.
