Tools and Die
High pressure die casting
Tools and Die Within the excessive stress die casting course of the metallic is pressured right into a excessive grade metal device at excessive velocity and -pressure. The casting temperature is roughly 700°C throughout casting. The usage of vacuum casting expertise is a bonus in an effort to obtain superior high quality for mild and skinny walled elements.
Excessive stress die casting is a aggressive casting technique when elements have necessities which can’t be achieved by different casting processes comparable to:
- excessive volumes and/or
- higher tolerances and/or
- clean floor end
The necessity for machining is comparatively low as a result of shut casting tolerances. The tooling prices are typically greater than for gravity die casting or low stress die casting.
Alteams manufactures excessive stress die casting in Laihia (Finland), Lebork (Poland), Suzhou (China) and Chennai (India)
Low strain die casting
Within the low strain die casting course of the metallic is transferred from an air tight furnace by means of a rising tube right into a metallic instrument. The casting temperature is about 750°C.
Low strain die casting is aggressive casting technique when the manufacturing amount is comparatively small and/or when warmth remedy is required to enhance the mechanical properties. The tolerances and the floor end are the identical as achieved by gravity die casting. The tooling prices are considerably greater than by sand casting.
Alteams manufactures low stress die castings in Laihia and with sand cores in Loppi, Finland.
Gravity die casting
In gravity die casting molten aluminium is poured right into a metallic instrument. The casting temperature is about 750°C. The tolerances and floor end are good. Using sand cores in gravity die casting permits casting of very advanced parts.
Tools and Die
Gravity die casting technique is aggressive casting technique when manufacturing amount is comparatively small or when warmth therapy is required to enhance the mechanical properties. This casting technique provides higher tolerances and floor end than sand casting. The tooling prices are considerably increased than by sand casting.
Utilizing sand cores in gravity die casting makes it potential to fabricate objects with sophisticated internal shapes in a price efficient method in small and medium portions. Typical merchandise produced this manner are e.g. air consumption elements for diesel engines, valves for stream techniques, tanks for air con methods and so on. Usually they’ve curved internal shapes that are optimized for fuel or liquid movement. Utilizing shell sand cores provides shut tolerances and comparatively good floor high quality additionally for the surfaces solidifying in opposition to the sand core. Alteams Loppi manufacturing facility has over 20 years of expertise with making use of this methodology for varied industrial functions.
Alteams manufactures gravity die castings in Laihia and Loppi, in Finland.
The sand casting technique consists of a furan resin bonded sand mildew into which melted steel is poured at about 750°C. The sand is sure with furan resin, which is chemically hardened at room temperature by mixing it with acid and sand. Plastic and wooden are used as materials for the casting sample at a comparatively low price.
Sand casting is appropriate additionally for giant castings utilized in small or medium portions. On account of comparatively low tooling prices the casting technique can be utilized for prototype manufacturing. The floor end and casting tolerances are enough for many functions.
In Alteams sand casting foundries it’s doable to provide aluminum castings with pouring weights as much as 950 kg and mildew weights as much as 6 tons.
Alteams produces additionally bronze (G-CuSn10Zn) castings by sand casting technique. Typical casting weights are 1 – 15 kg, max. weight as much as 1000 kg.

Shell mould casting
Within the shell mould casting course of wonderful sand is poured on a heated metallic sample. The resin bonded sand hardens ranging from the steel floor and create a roughly one centimeter thick shell. The shell is lifted off the mannequin and glued along with the opposite shell half to make the sand mould. Then molten steel at roughly 750°C is poured into the shell sand mould.
Shell mould casting is appropriate for skinny walled merchandise with good floor end necessities. The usage of sand cores additional extends the product vary. The shell mould casting course of offers a greater floor end and nearer tolerances than the sand casting. It’s potential to solid skinny walled merchandise at shut tolerances. The preliminary tooling value is larger than for sand casting.(Tools and Die)
The shell mould casting methodology is nicely relevant for pre-series of strain die forged elements. The floor of the casting is processed to be fairly just like a strain die solid one and excessive accuracy of dimensions might be achieved by further machining. Shell mould casting is appropriate when adjustments in the course of the product growth section must be simply and rapidly carried out.(Tools and Die)
