Moulded-in inserts resist twist and pull-out

Edited by the Manufacturingtalk editorial team May 19, 2004

Brass moulded-in inserts feature hexagonal heads and a large centre undercut to provide a high level of bi-directional torque resistance and contribute to high pull-out/pull-through strength.

Spirol Industries, the leading supplier of engineered fastener solutions, have introduced a new range of brass Moulded-In inserts.

They are designed to be placed in the plastic mould prior to plastic injection.

Two types of Moulded-In insert are available: Series 40 is a through hole type and Series 44 a blind end type.

Both types feature hexagonal heads and a large centre undercut to provide a high level of bi-directional torque resistance and contributing to exceptional pull-out/pull-through resistance.

The Series 40 also has generous internal counterbores to allow quick and easy installation on to guide-pins.

An internal minor thread is designed to eliminate insert wobble on the guide-pin.

Moulded-In inserts, like Spirol's renowned brass expansion range, do not require any specialised insertion tools.

The operator simply places the insert directly into the mould prior to plastic injection.

The inserts design simplifies orientation and placement on to the mould core, thereby increasing productivity and reducing potential scrap.

Literature is a variable on the new range directly from Spirol Industries.

This new range is the latest addition to the company's range of engineered insert solutions.

Rather than providing off the-self products, the company provides a full technical advisory service to all OEMs to ensure specification of the most appropriate Spirol product and installation methods.
