Water Flow Regulators

Why we use this unit?

do you know? How many problem are caused in plastics processing, while not regulating the flow of cooling water?

injection moulding

• short shots: mould is cold ununiform mould temp.
• sink marks: product too hot when ejected.
• brittleness of components: mould surface is too cold.
• bubbles and voids: condensation on cavity surface.
• surface lamination: - mould surface & too cold.
• surface waviness (pits orangeped, wrinkles): mould surface is too cold.
• warping: mould cooling uneven
• poor weld line. Mould too cold.
• dimensional variations ununiform mould temp.
• gate smear: mould temp. Not enough.

blow moulding:

• poor gloss : mould is too cold.
• rocket bottoms : insufficient mould cooling.
• parts sticking :mould too hot.
• rough grain surface: mould temp, very high
• warpage : insufficient cooling, non-uniform cooling

thermoforming:

• chill marks : mould too cold
• warping : improper cooling.
• blush or change in colour intensity: mould is too cold.
• bad surface marking : mould is cool.

pet bottles:

• short shot : improper cooling.
• crystalline haze check for proper cooling.

pet preform:

• splay marks : prevent condensation. .
• preform sticking and destoring : decrease mould temp.

Water flow regulators for mould cooling

the essential equipment for every injection moulding, blow moulding &. Thermoformlng machine.

we offer our well manufactured water flow regulators for mould cooling. It helps solving various problems in plastic processing by simply regulating the flow of cooling water. It has been observed that following types of problems occur due to improper regulation of water flow in various moulding processes:

operation

flow regulators provide exact control of waterflow to different cooling circuits. Visual indication, of the waterflow in each tooling zone and thereby exact and quick reproducibility after mould changes

advantages

• simple and compact design.
• dependability due to robust construction, all working pails including brass control valves for supply and return.
• precise control arid perfect seal of each circuit.
• easy connection for water supply and return on the side of the manifold and of each cooling circuit by hose nipples.
• high durability since all connections are made in metal.
• easy cleaning of indicating pipes as they are quickly removable via bayonet coupling.
• suitable for open and closed cooling circuits.
