Mock Ups Cubing Models 75mm Medium Density Epoxy Tooling Board

Medium density epoxy cutting tooling board for mock-ups Cubing models
 
Typical Applications
 
LH 5120 Epoxy Tooling Board can be used to produce highly accurate patterns and moulds. Patterns can be used to produce high volume composite moulds, including using prepreg tooling systems (with cure temperatures up to 130°C) and where dimensional stability is critical.
For smaller production runs LH-5120 can be used to produce the working mould itself. In this situation the machined mould - once suitably sealed and prepared - can be used as a mould/tool for the production of composite parts, including the manufacture of prepreg composite components (oven-only or autoclave cure).
 
In today's world rapid growth of composite materials industry, polyurethane die plate is also more and more in CNC machining die and use. Polyurethane panels are superior to epoxy in many properties and can produce high precision moulds. Moulds made from polyurethane moulds remain accurate in size after many years of storage because they do not shrink over time and are not affected by moisture. In recent years, with the demand of end customers for high quality, in order to improve economic benefits, polyurethane board has become a trend. In order to greatly save cost, different products can be made at the same density, and products of this quality can also be made at the same hardness. Another trend is to use machined epoxy mould paste. It is formed by a mixture of two parts AB and 1 to 1, which is then CNC processed, and the mold paste allows the use of very low density foam to fill the plug or the mold's internal volume. The core of the foam is covered with tool paste. After curing, the epoxy shell is CNC machined to form a very dense, very durable, high-temperature mold surface that can maintain a vacuum and withstand multiple draws.
