Permanent mould casting

Basic product information

Materials

E-Cu - high conductivity copper and a wide scale of copper, bronze, brass and aluminium materials.

Dimensions

Aluminium alloy castings, max. size: 350 x 600 mm.

Copper alloy castings, max. size: 250 x 250 mm / 200 x 350 mm.

Maximum dimensions depend on the casting shape.

Max. casting weight: 8.5 kg.

Tolerances

Tolerance class: as per DIN 1687/1688 - GTA 14 applicable to permanent mould casting.

Quality

Quality control is a fundamental element of our permanent mould casting process. It starts from the receipt of materials and is maintained across the entire manufacturing process.

Our quality management relies on an integrated quality management system conforming to ISO 9001:2008. We are also holders of certificates P.E.D., ISO 14001:2004 and OHSAS 18001:2007.

Industrial applications

Our castings are suitable for all industrial sectors where metal parts are used.

Our customers include large machinery corporations as well as specialist small firms manufacturing to order.

Sectors to which we supply our castings include machinery engineering, electrical engineering, telecommunications, road and railway transport, and many others.

Benefits of permanent mould castings

  • Ability to cast sophisticated inner and outer shapes 
  • The high rate of cooling during the metal solidification in a permanent metal mould delivers increased alloy thickness and fine-grained structure of the casting, and excellent mechanical properties as a result 
  • High dimensional and shape stability and precision of castings
  • Excellent casting surface quality which allows reduction of machining additions and thus reduces/eliminates the machining 
  • Significantly lower material consumption as compared to conventional casting methods
  • Permanent mould casting is suitable for both small- and large-series production

Technical assistance and customer project support

Our aim is to work jointly with our customers and contribute to their casting projects already from the design stage. Series production starts only when the casting design has been optimised. The result is top casting quality at a low price.

Permanent mould casting process

Step one: The casting design is made according to the customer's final part drawing. Based on the casting drawing, the mould is designed and drawn, and then made according to the drawing.

Step two: Sampling, trial casting and subsequent quality control. Series production is launched only after the samples have been approved by the customer .

Step three: After the approval of samples, the series casting is started. The melted metal is poured directly into the mould. Metal core elements provided inside the mould allow the inner shapes, and secure dimensional and shape precision as well as high surface quality of castings.

Step four: Castings are cut away from the runner system and undergo the final finishing by grinding, deburring, sanding or tumbling.

Step five: Depending on customer's wishes, castings may undergo further heat treatment and machining.

Heat treatment and mechanical machining of castings

Depending on customer requirements, some castings may receive heat treatment and undergo further mechanical machining. Most common casting machining operations include drilling, milling and turning. Other special machining operations can be delivered on demand.

Surface quality

MEDEKO makes efforts to deliver a product that is completely finished. Where the casting requires further surface treatment, we are able to provide plating with zinc, nitride, or nickel; polishing; electrolytic polishing; lacquering; powder lacquering.

Mould manufacture

We employ the most advanced technologies in the mould manufacture, including 5-axis machining centres and latest CAD system versions. High-quality design and workmanship of the mould are the key to a high-quality casting.
