Products are stored to wait in raw material inventory before processing.


ASP is able to supply more than 10.000 spare parts in the Caterpillar line.

Firstly, the type of the material is determined by doing the physical tests and chemical analysis of the original sample .Then the process will go on with reverse enginering; the equivalent materials on the market are researched and in case of need, it is aimed for producing these parts more robust and durable than the original by improving them.
After being sure of the quality of the material, the technical drawing of the sample is graphed and right after that the moulding and modeling are done.
The surface controls and X-rays of the Raw Materials, which are casted in supplier's foundry, using high capacity and advance technology , are made after going throught test phases in laboratory .
Materials reverted to facility from the suppliers, are produced sensitively on the CNC workbenches.
The production process goes on by subjecting one in every 5 parts in production to measurement controls in CMM measuring device .All processes are followed by engineers using ERP system.
After being controlled at the final inspection station with %100 measurement controls, the end products are painted with protective oil, stored with appropriate packaging and made ready for shipment.
The certificate of analysis , processing time, cost account, operation records, conformity and quality reports of each part , are recorded indivudually and archived.


The most important processes are made within ASP Machinery .

In addition to many processes used for production of spare parts, we also perform the process of robot welding, heat treatment, induction, grinding, balancing, threading, painting and finally the most important process of testing and analyzing the parts with product testing devices .


Quality is among the ASP's primary goals .

All supplied and produced spare parts are subjected to test series before being released to the market. Tests and controls start from the first steps of the production and go on to the end. All these tests and controls ; raw material analysis, laser measurement, hardness tests, run tests and quality controls for end products respectively,are performed in ASSAN-ASP laboratories.

Assan achieved the ISO 9001: 2000 certificate in 1996. This not only has certified the quality and professional organization of ASSAN but has also marked ASSAN as a reliable producer in the market. This quality certification has aimed ASSAN to reach higher and is a top priority in the company.


ASP, which keeps annually more than 1.2 million products in stock ; follows studiously the chain of packaging, shipping and modern logistics systems.


Whatever your demands, we are your solution partner in the service and spare parts area.
