Mold and Die
From our founding in 1969, TARUS has been deeply rooted in the mold and die industry. Serving a customer base in the middle of the mold and die industrial base of North America means that almost every production passenger vehicle in the US contains components that TARUS machines have played a role in producing. TARUS' reach extends beyond into various industries like aerospace, defense & military applications, power generation, oil & gas, and more.
Starting with EDM machines in 1969, TARUS later created the Duplicator which was our first CNC Mill and a runaway sales success in the 1980’s. TARUS now offers leading gantry, bridge, and horizontal arm 5-axis mills with the latest high performance CNC from Heidenhain and Siemens.
Starting in 1973, TARUS was the first company to create purpose-built deephole drilling (gundrilling) machines for mold makers. TARUS gundrilling machines are the most widely used gundrilling machines in the large mold industry in North America. In addition, our CMM line has achieved a number of important innovations, and TARUS has been a pioneer in software development for the mold and die industry.
TARUS machines are legendary for their toughness and durability due to their design and structural integrity. It is very common to see nearly 50 year old TARUS machines in daily operation with maintenance and upgrades.
Mold and Die
A plastic preform is heated and filled with pressurized air inside a mold, and the resulting shape is the the container or vessel for fluids. Common applications are gas tanks, reservoirs for coolant and power steering fluids, ducting and tubing.
Bond Fixtures/Layup Molds
Bond fixtures and layup molds come in a variety of types, including Invar, steel, aluminum, carbon fiber, and hybrid Invar and composite. TARUS 5-axis CNC machines are commonly used to in the aerospace tooling industry to manufacture these tools.
Compression molding is a forming process in which a plastic material is placed directly into a heated metal mold then is softened by the heat and therefore forced to conform to the shape of the mold, as the mold closes. Compression molding applied to automobile and heavy truck body applications typically refer to SMC or Sheet Molded Composites.
Die casting is a manufacturing process in which molten metal is forced into steel molds. The advantage of this process is the accuracy and repeatability compared to traditional pour casting. Die cast automotive components include aluminum transmission cases, bell housings, suspension components, and bulkheads. TARUS machines are utilized in the production of the die cast die as well as machining the cast aluminum components.
Forging dies are consumable tooling used in the process of manufacturing highly durable automotive components such as connecting rods, crankshafts, differential gears, and steering arms.
In 1973, TARUS unveiled our first gundrilling machine which was designed for injection mold and die cast die builders. TARUS was the first company to build purpose-designed gundrilling for drilling large molds and we continue to be the leader with our DHDM deephole drilling and milling machines
Hydroforming is a specialized type of die forming that uses a high pressure hydraulic fluid to press room temperature working material into a die. Hydroforming allows complex shapes with concavities to be formed, which would be difficult or impossible with standard solid die stamping. Hydroformed parts can often be made with a higher stiffness-to-weight ratio and at a lower per unit cost than traditional stamped or stamped and welded parts. Virtually all metals capable of cold forming can be hydroformed, including aluminum, brass, carbon and stainless steel, copper, and high strength alloys.
Injection molding is a manufacturing process where melted plastic is forced under pressure into steel or aluminum molds. These molds are cooled by liquid to solidify the part.
Stamped and molded components are measured using a coordinate measuring machine (CMM) after forming and before assembly to ensure quality and precision.
Pellet dies typically come in two forms, either flat or ring-shaped. A roller forces raw material or feedstock under intense pressure to produce pellets. Pellet dies are driven by the main motor of a pellet mill. Pellet holes and thickness of pellet die determine the pellet size and features. Common applications are livestock feed, pet foods, scientific, medical, and biofuels.
Prototype/Low Volume Stamping Dies
Prototype stamping dies are used for body development, and building vehicles used for crash testing. CNC machines are used to mill precise contoured surfaces into the Kirksite prototype stamping die.
Roto molds, or rotational molding, involves a heated hollow mold which is filled with a charge or shot weight of material. It is then slowly rotated (usually around two perpendicular axes), causing the softened material to disperse and stick to the walls of the mold. In order to maintain even thickness throughout the part, the mold continues to rotate at all times during the heating phase and to avoid sagging or deformation also during the cooling phase.
Stack molds have multiple mold parting surfaces or mold split lines in one mold. Instead of increasing the mold size by adding more cavities, a stack mold maintains mold size and machine size by adding a second layer of cavities parallel to the first layer.
Stamping dies are used to form steel and aluminum body panels, chassis components and other automobile components.
The TARUS UNIMAX series are ideal for milling engraved tire tread molds due to the universal milling head and rotary table configuration.
