Abstract
Abstract The article deals with the assessment of production process capability in the serial production of plastic components. The plastic component was used for analysis. Component is used in the automotive industry in car suspension shock absorbers. Assessing the capability of the product’s manufacturing process is very important. The aim of the present paper is to measure the dimensional characteristics of a thermoplastic product as a monitored quality feature. The analyzed product is manufactured in an eightfold injection mold by injection technology. The products from each injection mold cavity were considered separately. Process capability was assessed using capability indices. Process variability and centering were evaluated. Based on the analysis we can say that the production process is in excellent condition.

Quality and stability of the production process are notions associated with the regulation procedures
Summary
Regulatory procedures serve to assess and improve the quality and stability of production processes. The implementation of statistical methods is a simple tool for monitoring the production process. They can be used to identify the causes of process instability. Statistical process control is a simple method used to control the quality of production processes. The information on capability of the production equipment and production process allow assessing of the extent of the variability of processes coming from other sources such as, for instance, influence of material, of operating, of maintenance, etc. The capability of the production process reflects its overall uniformity It is characterized and represented by process variability. The process capability is a statistical measure of the inherent process variability represented by the relevant characteristics.
