Mitak

Mitak has been producing high chrome wear-resistant castings for more than 40 years. Most of the alloys it casts conform to various international standards, including DIN EN12513 EN-GJN-HB555, BS4844 Grade 3 and ASTM A532 Class II and III. These alloys typically have a chromium content of 12% to 35% and carbon of 1.8% to 3.5%.

Focused
The fact that Mitak only makes high chrome white iron materials places the company in the privileged position of being able to tailor each stage of the manufacturing process to one material class, from pattern manufacture to melting, heat treatment and inspection. This offers great advantages to customers: It creates efficiencies that reduce costs, while offering even more consistent quality and greater accuracy of on time delivery.

Capacity
Mitak has large capacity and manufactures more than 800 tons per month of finished mass for the mining, dredging, construction and power generation industries. This is made up of equipment that is used mostly in pumping, grinding, crushing, separation and general materials handling applications.

Certified
The company is ISO 9001:2008 certified and has a safety and environmental department that maintains strict standards, with the goal of OHSAS 18001 certification by 2020.

Global
More than half of Mitak’s production is exported. This global mindset gives Mitak the ability to service diverse needs, overcome complicated logistical challenges and meet world class standards in all aspects of supply.

The Mitak Team
Above all, Mitak is about its people – a committed team of more than 500 who through dedication and experience produce castings that surpass the most stringent quality standards. It is this collective talent that is behind each and every casting Mitak produces.

Moulding
Mitak offers complete versatility in its range of supply. It moulds and casts parts that weigh as little as 0.5kg and as much as 18 tons. This diversity of supply is made possible by having 10 different foundry moulding bays, each with its own equipment customised to manufacture a specific size and quantity of part. The moulding equipment ranges from high-volume semi-mechanised production to jobbing-type floor moulding with boxes up to 4.5m (15ft) in size.

Melting
Mitak operates six induction furnaces that range in size from 4 to 12 tons. The moulding bay where the heaviest castings are made utilises 40-ton cranes. The compositional accuracy of each melt is ensured via two optical emission spectrometers.

Heat treatment
12 heat treatment furnaces give Mitak the capability to heat-treat a wide range of components up to 5.2m (17ft) in diameter. Each furnace is equipped with temperature management systems and dedicated air-quenching capabilities.

Machining
Mitak’s machine shop has great versatility: it can handle the machining of large or small components and production or jobbing batch sizes. The largest machines are capable of turning up to 5.4m in diameter and 5 axis milling with a work area of up to 5 meters in length.

Mitak has customised many aspects of its machining plant to the features of the specialised parts made. An example of this is that each centrifugal pump impeller is rotationally balanced.

Quality control
The quality control team at Mitak comprises more than 40 people who are driven by the goal of zero customer rejects. With the backing of an entirely online quality management system, they perform in-process and final inspections on the thousands of parts supplied each month. They utilise hi-tech measuring equipment – including the latest laser scanning technology – to meet customers ever increasing demands for more accurate cast components. The end result is castings of the highest integrity.

Logistics
Mitak offers customers the peace of mind to package and ship their components to any destination on the planet. Mitak has agreements with many leading shipping lines and provides cost-effective transportation solutions on an LCL, FCL or airfreight basis.
