Foundry Tooling - Patterns Permanent Molds

Sand castings make up roughly 70% of cast parts and red board patterns are usually the cheapest / quickest option while still maintaining a good surface finish

• Cost - red board is easier to machine saving you money.

• Durability - compared to older wood patterns, red patterns last longer and have better finish quality.

• Short lead times - maching redboard is faster, helping to get your tooling produced quickly.

Aluminum patterns provide a more stable option and allow for thinner parts. When parts have complex geometry, offset partings or they are thin, machined matchplates are the best option for thin parts.

• Durability - compared to wood or red board patterns, aluminum patterns last longer and are more stable. They can also be welded making repairs and changes easier.

• Cost - aluminum tooling is more affordable for medium to high volume runs compared to a permanent mold.

• Fully Machined Aluminum Matchplate - Choosing a fully machined aluminum matchplate allows you more flexability. Gating can be machined in making tooling easier to manage, machined matchplates have lower scrap rates saving you money.

If you plan on very high volumes or need extremely nice surface finish, permanent molds are the preferred option. Common metals cast in Permanent molds include: aluminium, magnesium, copper, tin, zinc, and lead alloys.

We are experts at core assemblies and try to save you money by eliminating them whenever possible. When cores are needed we can assist you in the design of core assemblies small or large. Once designs are produced we can machine coreboxes usually called cold boxes when made from red board or shell boxes when made from iron.
