Metal Injection Molding
Ünimetal produces small, precise, high-volume parts with complex geometry by metal injection molding (MIM). After mold design and manufacturing by its engineering team, parts that need rapid prototyping, high-volume production and high strength are supplied with MIM technology. Annual capacity is stated as 4 million parts. Parts developed through its engineering work are produced for customers in the automotive and machinery sectors.
Investment Casting
Ünimetal casts complex parts from steel in the range of 0.5 g to 105 kg and from aluminum in the range of 10 g to 50 kg. Normalization and stress relieving for steel, and solution treatment and aging for aluminum alloys, are carried out in Ünimetal facilities. The route covers mold design and manufacturing, wax model production, wax assembly, ceramic coating, dewaxing and casting, then ceramic shell breaking, cutting and resetting. Steel melting is stated at 175 tons per month with two 2 x 150 kg double-pot induction furnaces, and aluminum melting at 35 tons per month with 500 kg and 300 kg furnaces.
Machining
In machining, deadline and cost advantages are taken from the shape and design flexibility of the investment casting process. The flexibility of the machine park supports machining for parts of different types and sizes. Surface integrity, total process cost, use of energy and other resources, waste reduction, and occupational health and safety are assessed together with precise measurement. Machined and assembled products are offered on new-generation milling and lathe machines. Product traceability and lot tracking are used for control at each machining stage and for improvement from data reports.
Services
Turnkey Projects
In turnkey work, engineers and technical staff work with the customer from the project stage through delivery of the finished product, aiming to produce the requested part under suitable conditions. Mold design and production, casting, machining, heat treatment, surface protection and assembly are organized under Ünimetal’s own management and delivered as a finished product. Ünimetal states that it produces part-based or turnkey products and projects for organizations in energy, automotive, railway, medical, and fine arts and architecture.
Rapid Prototyping and 3D Printing
In the rapid prototyping service, the 3D data and technical drawing sent by the customer are delivered as a casting within 1 to 4 weeks, depending on part geometry. Advanced 3D printers are used. The method is presented as an alternative to the high cost of machining samples from solid material, so the first samples can be designed for casting from the start. Lead times before series production are brought forward, and low quantities are made to the requested measurements without giving up geometry or size and without a high mold investment. Many small parts can be produced in one work package, and design errors can be seen before series production.
Design Services
The design service turns ideas into practicable designs for metal casting, depending on whether function, material, technique or aesthetics has to come first. Experience and the engineering team determine which factor should lead in a given case. With current hardware and software, the final product or component the customer needs is designed for form, material and cost. On the mold side, technical variables are set with CAD and CAM software, and molds are tested in a simulation program for ease of use and service life before physical production.
