“…In case of detecting at the client non-compliant parts the supplier is obliged to immediately implement the Controlled Shipping procedure (sometimes also called Restricted Shipping).Controlled Shipping process assumes the introduction of an additional 100% inspection of section at the end of the production process or outside the production line, in order to search for parts of nOK, according to the accepted instruction. Controlled Shipping provides an immediate opportunity to protect the customer from receiving further non-compliant parts, and to the supplier gives time to find the root cause and to implement corrective actions [23][24][25][26]. Control in the process of Controlled Shipping can be visual or using specific control and measurement tools or gauges.…”

Providing high quality of products not covered by defective products is an important part of the supply chain between the manufacturer of the automotive parts and the final assembly company. The paper presents the results of research related to determining the effectiveness of quality control in a company producing plastic components for automotive industry at separate levels. Upon detection of nonconforming products at his plant, recepient according to the contract asked the supplier to launch the Controlled Shipping Level 1 procedures. As a result of the lack of significant improvement, there was run in the supplier’s plant the Controlled Shipping Level 2 procedure realized on an outsourcing basis by specialized external company. Presented results of the research have made it possible to determine the effectiveness of carried out control activities. Carried out research, also confirmed by expert interviews, show that automotive companies aim to make their business more flexible so that they respond faster and more easily to internal and mainly external factors. What in the opinion of production and quality managers provides outsorcing of quality control.

“…According to the results of our earlier experiments [34][35][36], the following values of the parameters of the electrostatic separation process were applied: A design matrix elaborated and presented in [37] was used in this study. Since six types of the binary mixtures were examined and each mixture consisted of 30 samples, the total number of experiments was 180.…”

There are presented results of investigation of electrostatic separation of binary mixtures containing a biodegradable polymer {polylactide (PLA), polycaprolactone (PCL), or poly(3-hydroxybutyrate-co-4-hydroxybutyrate) [P(3,4HB)]} and a commonly used polymer [poly(vinyl chloride) (PVC) or poly(ethylene terephthalate) (PET)]. It was found that the binary mixtures of these polymers could be efficiently separated. The electrostatic separation process of the P(3,4HB)/PET mixture appeared to be most successful. It is indicated that the share of a biodegradable component in the mixture essentially influences the separation effects. Therefore, suitable choice of necessary conditions is needed to perform the separation process, which includes appropriate separator settings, depending on fractions of individual components in the mixture being separated.

“…The main risk factors for failures are equipment wear [23][24][25], failures of structural joints, including welded joints [26][27][28], and unwanted gas and liquids ingress [29][30][31]. Preventing failures requires the use of materials with desired technological and functional properties [32][33][34], and in specific cases, complementing them with coatings that modify their characteristics [35], including coatings with special functional properties [36][37][38] and those that alter mechanical properties [39][40][41].…”

Numerical Analysis of a Pneumatic Cushion Operation Safety, including the Airflow Conditions

Abstract. This work concerns studying the characteristics of a pneumatic cushion in a system for moving heavy loads. Particular emphasis has been placed on the airflow parameters through the main supply nozzle, including the average flow velocity. Critical flow at the speed of sound can occur under certain circumstances. In the subsequent steps, a mathematical model of a pneumatic cushion was formulated, next, a simulation model was built in the Matlab/Simulink system, and then numerical simulations were carried out. As a result, it was estimated whether there is a flow with a safe, appropriately low speed in a given range of load and supply pressure.
