To ensure on time delivery of highest quality parts to our customers, we are getting all the help we can from the technology in the casting industry:

1- CNC


VM 100 N - Vertical CNC

TC 200 B - Horizontal CNC

2- CASTING PROCESS SIMULATION

HIGH PRESSURE DIE CASTING



Optimal piston velocity profiles, gating designs and overflow positioning can easily be achieved with simulation even for very thin walled
structures. Thermo-mechanical die cycles can be performed to address not only the issue of die life but also in-service part performance, thus reducing manufacturing risks and costs.



High-pressure die casting

LOW PRESSURE DIE CASTING

To reproduce industrial production conditions, mold cycles can be performed numerically until the mold has reached steady state temperature conditions. Based on thermal die profiles, mold filling and solidification results, process parameters can be tuned to achieve optimal process quality while reducing time to market.

LOST FOAM PROCESS





The simulation of lost foam processes requires a detailed physical modeling of the counter pressure generated by the foam combustion as well as the effect of the permeability of the coating and sand. Simulation provides an accurate solution to the complex physics behind lost foam processes.

POSSIBLE SIMULATION PROBLEMS IN CASTING:



*Metal front progression



*Solidification simulation



*Part deformations


 

*Metal front progression around a core.









*Metal and air visualization in high pressure die casting










*Porosity prediction




*Shrinkage prediction



Microstructure module:
A deterministic model.

It computes solidification and solid state transformations quantitatively and qualitatively. The evolution of the various phase fractions, as well as their related heat release, is derived from physical microstructure models. Phase compositions such as austenite, ferrite, cementite, graphite, pearlite and martensite can be predicted. It also provides further micro-structural features and material properties such as nodule counts for spheroidal iron and hardness distribution.

3- QUALITY CONTROL

SPECTROMETER: Ersa Foundry utilizes Spectrolab brand spectrometers to identify the chemical composition of the samples.

Before the casting process starts, from each load and ladle, samples are taken. Depending on the results of the metalurgical analyses done by the machine, after necessary chemical interventions, upon reaching the desired measures, casting process takes starts.

After the comparative chemical analyses of the samples received from the customer and the ones produced in the foundry, the chemical sameness of the samples are strived to reach by the help of the spectrometer. The samples are then forwarded to quality control department for further analysis.


 
 
 
Ersa foundry operations has started in Aliağa, Turkey.

As of January 2006, Ersa foundry operations has started with very knowledgeable and dynamic ,ambitious group of people, aiming to become a leading manufacturer of automotive and construction machinery spare parts, specializing in ductile, high sillicon moly, cast iron spare parts.

 

Ersa Döküm has begun casting process in its brand new location in Aliağa, İzmir. As of January 6th, 2006, Ersa has moved its foundry operations to Aliağa Industrial zone in İzmir.

In a lot of 13.000 m2, a new foundry and CNC center is built in an area covering 6.500 m2.

 
Ersa Foundry obtained TS EN ISO 9001: 2000 TUV NORD Certificate in September 2004.
