SPLIT INSERTS

FOR INSERTION BY EXPANSION IN PLASTICS

As with all our SERPLAST inserts,

the shape and configuration of teeth formation avoids any movement or rotation, even when a very high tightening torque is applied. Our SERPLAST inserts absorb stress and evenly spread loads ensuring a solid and permanent mounting.

SERPLAST TYPES TR, DM, C, CM

ADVANTAGES

•They provide a resistant internal threading for plastic materials and suitably replace cast moulded inserts.

^ Positionned after moulding, either manually or automatically, they allow substantially higher production rates.

• Deterioration of internal threading in plastic parts is done away with. ^ Very precise positioning.

^ If the insert to be cast moulded has not been positioned exactly right, it avoids to damage the cast when closing.

APPLICATIONS

SERPLAST can be used with all types of plastic. SERPLAST TR is for thermoplastics ; SERPLAST DM is for duroplastics. They are inserted in a special hole that has been moulded or drilled.

MATERIAL AND FINISH

SERPLAST TR-DM INSERTS are made of brass and can be zinc or nickel coated.

MOUNTING

By simple manual pressure, the SERPLAST INSERT fits into the hole made for it, no special tooling is required.

2 Push in manually or automatically.

1 Position the insert in the hole.

It is anchored in position when the screw spreads the insert lips out and the sharpened teeth penetrate the wall of the hole so fixing SERPLAST in position.

Dimensions indicated in this table are not limited. We can manufacture any SERPLAST INSERTS that can be needed.

To ensure solid mounting, the threaded length of the screw to be put in the SERPLAST insert must be at least the same length as the insert.
