Detailed description of castor rubber coating
Different base materials shall be coated with different materials. For example, PP can not be wrapped

with ABS, ABS can not be wrapped with PA, etc. At present, the rubber coated TPE in the market can

be divided into the following categories: PP rubber coated, ABS rubber coated, PETG rubber coated,

PC rubber coated, PA rubber coated, etc.

Thickness of TPE coating:
In most rubber coated molding applications, good bonding effect can be guaranteed when the wall

thickness range is 1.5-3.0mm. If the TPE glue position is too thin, injection molding is difficult, the

bonding strength is low and the hand feel is poor. If the TPE glue position is too thick, on the one

hand, the cost is high, on the other hand, it is easy to produce shrinkage, bubbles and other defects.

The wall thickness of TPE glue position shall be as uniform as possible to achieve the best forming

cycle. The transition between different wall thicknesses should be gradual to reduce problems caused

by fluid flow, such as gas ripples and bubbles.

Radian (minimum radius 0.5mm) shall be used at sharp corners to reduce local stress. Deep closed

air chambers or arched parts that cannot be vented shall be avoided. If necessary, enough exhaust

slots (0.015-0.025mm) can be added at the end of TPE glue position. Insufficient exhaust may cause

gas trapping, glue burning, insufficient adhesion and other adverse phenomena.

It is helpful to improve the bonding effect of TPE by adding buckle on the substrate or making some

properly designed deep concave convex parts. Treatment of die surface:

The mould shall be polished to obtain a smooth or clear surface. In order to produce the dull

appearance of thermosetting rubber surface, a rough mold surface is needed. Generally speaking,

the rough surface of the die cavity after electrical discharge machining (EDM) will produce a good

workpiece appearance and make demoulding easier. Grinding methods such as steam jet, sand blast

or shot peening and chemical etching can also be used to produce surfaces with different gloss and

appearance.

In order to facilitate demoulding, a layer of demoulding coating can be applied on the mold cavity or

core, for example, a layer of nickel impregnated with PTFE (polytetrafluoroethylene) after sand blasting

or electrical discharge machining (EDM).

The use of release agent shall be avoided for the base material. The surface of the substrate shall be

clean and avoid contacting dust as much as possible.

The processing temperature of TPE compound shall be subject to the measured melting temperature

of the compound, rather than the displayed temperature of the injection molding machine.
If TPE is required to be coated on metal parts, appropriate adhesive can be used as an auxiliary.
