CAST KIRKSITE TOOLING PDF

Because we embrace the technology of today and tomorrow! Kirksite tooling is just one process that we utilize to meet the needs of our valued customers. The vapor pressure of the zinc allows the material to be virtually immune to the gas porosity that occurs with other alloy products. This results in a shrinkage rate that is approximately half that of aluminum, which allows for precise cast mold accuracy and repeatability. The process for casting Kirksite begins with creating a master pattern that will compensate for shrinkage. Then a sand impression is taken from this master pattern to create the core and cavity set.

Kirksite is a moderate strength zinc-base alloy that was developed primarily as a forming tool alloy. Dies cast from Kirksite provide low-cost tooling because the alloy can be accurately cast, requiring a minimum of finishing. In addition, Kirksite has been used as a general purpose casting alloy for non-stressed components. Typical uses for Kirksite alloys are: Press dies and punches for sheet metal forming. Molds for ceramics and rubber. Injection molding and compression molding dies.

Tube bending dies. Mandrels for metal spinning. Low stressed non-sparking tools and repair parts. Higher casting temperatures should be avoided due to possible iron contamination from the cast iron kettles normally used to melt the alloy. Iron pickup can cause poor casting surface quality and brittleness.

Melting in a silicon carbide crucible is preferred as a safeguard against iron pickup. The alloy is normally cast in permanent, plaster or sand molds. Kirksite is readily machined and polished. Castings can be successfully plated following procedures used for zinc die-castings. Kirksite can also be cast in rubber tooling as a replacement for slush casting alloy ZA-5 when higher strengths are required, with a sacrifice in fluidity.

Meztigul The molds are then mounted into a traditional injection press of the appropriate tonnage and parts are run. For this reason, new materials based on epoxy kirksiite ceramic capable of withstanding harsh operating conditions have been developed. With increase in accuracy of RP techniques, numerous processes have been developed for producing tooling from RP masters. If correct, the next page will load with a graphic first — these can be used to check. By First-rate Mold Solution Co. The supports are subsequently removed and the mould is polished in the direction of draw to facilitate part release. In most cases, toolinh will have an appearance very close to the production parts and many OEMs have used the parts to market their product ahead of full-scale production.

Mold Base (Kirksite) Alloys

Kirksite tooling is a unique and valuable product offering and has helped make Experi-Metal an industry leader for over 55 years. While still an important standard for car manufacturing, its use has expanded into developing prototypes for industries including aerospace, aircraft and military defense. With a shrinking rate that is half that of aluminum, our engineers are able to build prototypes quicker with Kirksite than with any other materials. Even at a faster rate of production, the high quality of the material does not sacrifice accuracy. Due to its ability to be both machinable and weldable, design adjustments can be made relatively quickly.
