Product catalog summary

About EMKA Precision Casting
EMKA Precision Casting, part of the EMKA Group since 2015, operates in Mionica, Serbia, producing 4 million parts annually with 187 employees. The facility covers 10,479 m² and processes 400 tons of material each year. It is certified under ISO 9001:2015 and IATF 16949:2016 standards.

Services Offered
EMKA provides application consulting, project management, development and engineering, specialized design, series production, surface treatment, post-processing, certification, and logistics.

Technical Specifications
Parts range from 5 g to 10 kg, with lengths up to 250 mm, using steel and stainless steel. Heat treatments include hardening, case hardening, and tempering. Tolerances follow VDG P690 D2, and surface quality can reach N8 without reworking. Surface treatments include sand blasting, pickling, passivating, electropolishing, and grinding. Post-processing involves milling, CNC turning, and eroding.

Advantages of Precision Casting
Precision casting offers high dimensional accuracy, good surface quality, and design flexibility, allowing for complex shapes and low material input. It supports low wall thicknesses, a wide variety of materials, and is cost-effective compared to other methods.

Precision Casting Process
1. Wax Injection Process: Wax patterns are created in molds similar to plastic injection.
2. Create Wax Tree: Wax patterns are assembled into a casting cluster.
3. Creating the Mould: The cluster is coated with ceramic slurry and sand to form the mold.
4. Wax Removal: Wax is melted out, and the mold is fired for curing.
5. Casting: Molten metal is poured into the hot mold.
6. Demolition of the Mould: The ceramic shell is removed after cooling.
7. Separating the Parts: Castings are separated and machined.
8. Finished Cast Parts: Additional treatments and finishes are applied as needed.

Industry Partnerships
EMKA partners with various industries, including automotive, railway, agriculture, hydraulics, pneumatics, electrical, machine tools, medical technology, metalworking, and fitting parts industries.

Precision casting technology 1. Wax injection process The wax patterns are produced in moulds comparable to the plastic injection process and form a positive model of the casting to be produced. 2. Create wax tree The single wax patterns are attached to a central casting barrel and assembled into a complete casting cluster (also called a wax tree). 3. Creating the mould The actual casting mould is created by alternately immersing the casting cluster in a ceramic slurry and in fine sand. In this process, up to 9 layers are built up, which in the end represents the actual mould. 4. Wax removal...
