Mold Tech Texture -> Handling Information :

Handling Information :
Date:09.Apr.2006

 

A. Eyebolt Holes Required:

When a mold cavity, core, slide or other mold component is textured, it must go into an etchant bath or be positioned in front of an etchant spray through the use of an overhead crane. In order to safely and effectively process these components, we require a minimum of two and an ideal number of four Eyebolt holes of a size and threading compatible with the weight of the component being handled.

In the case of smaller components, for example, those that can be carried in one hand, eyebolt holes are not required, as we can place those pieces on a rack designed to carry them.

In the case of aluminum, even though weight is a less important factor, any piece of a size over 18" X 18" X 12" approximately should have eyebolt holes for proper processing at our facility.

This is a very important factor in the timing of processing your mold, since a lack of these holes forces us to either return the mold to you for holes or enlist the aid of a local toolshop to cut and thread the holes for us. Obviously, this slows down the process and adds extra costs not covered in the original quotation. Please note the
photo where we have attempted to show the proper position of eyebolt holes for purposes of texturing.


B. Disassembly and Reassembly:

In order to process most texturing , the mold component involved must be submerged into an etchant bath. Therefore, any area of the component that does not require texturing must be masked off by the use of various tapes, waxes, inks or paints . These masking tools protect the non-textured areas from etchant damage. In order to properly mask the non-textured areas, we have to be able to access them.

Therefore, in almost every texturing situation, it is best to send us only the component(s) that actually require the texture. This means that the mold should be disassembled, leaving those pieces, such as the core, slides or lifters, etc. that do not need to be textured, at your facility. This not only cuts down on unnecessary extra shipping costs due to weight, but reduces time delays.

We strongly recommend that you remove any back plates, electrical or hydraulic components, waterline connectors, horn pins, wear plates, guide pins, retainer rings, side locks, ID plates, limit switches or any component that would interfere with our ability to properly seal the mold piece for a dip into an etchant.
