Incoming control parameters for PVC sheets used for the production of plastic cards

One of the main requirements for obtaining high-quality raw materials for production is a clear formulation of the necessary parameters that the manufacturer of materials must comply with in the production of raw materials. The very observance of these parameters in the future will reduce the number of production of unsuitable products and plastic cards with defects. Parameter control is carried out for each separate batch of materials. The sample during inspection should be at least 0.1 % of the total amount of material, the deviation from the parameters should be included in the tolerance. The tasks of the stage of product quality control should ensure the implementation of the quality policy, as well as the general economic policy of the enterprise. Control is an integral part of the activities of any enterprise, a regulator of factors that form quality at all stages of the production process and ensure the release of quality products. Based on the analysis and experimental studies, the main parameters that need to be monitored were determined: geometric dimensions, color, thickness, density, surface tension, tensile strength, uniformity of paint application, shrinkage during sheet sintering

Towards Continuous Primary Manufacturing Processes—Particle Design through Combined Crystallization and Particle Isolation

Integrated continuous manufacturing processes of active pharmaceutical ingredients (API) provide key benefits concerning product quality control, scale-up capability, and a reduced time-to-market. Thereby, the crystallization step, which is used in approximately 90% of API productions, mainly defines the final API properties. This study focuses on the design and operation of an integrated small-scale process combining a continuous slug flow crystallizer (SFC) with continuous particle isolation using the modular continuous vacuum screw filter (CVSF). By selective adjustment of supersaturation and undersaturation, the otherwise usual blocking could be successfully avoided in both apparatuses. It was shown that, during crystallization in an SFC, a significant crystal growth of particles (Δd50,3≈ 220 µm) is achieved, and that, during product isolation in the CVSF, the overall particle size distribution (PSD) is maintained. The residual moistures for the integrated process ranged around 2% during all experiments performed, ensuring free-flowing particles at the CVSF outlet. In summary, the integrated setup offers unique features, such as its enhanced product quality control and fast start-up behavior, providing a promising concept for integrated continuous primary manufacturing processes of APIs.

Quality assurance and quality control. current furtherances and hereafter point of view

Quality assurance can be delineated as "section of quality management concentrated on furnishing confidence that quality must-have will be performed." The confidence delivered by quality assurance is twice intrinsically to management and extrinsically to clients, government agencies, regulators, certifiers, and third parties. An alternate delineation is "entire the aimed and organized activities accomplishment within the quality method that can be substantiated to hand over confidence that a commodity or service will perform must-have for quality. Quality assurance is across-the-board and does not have to do with the specific must-have of the product being developed. QA hobbies and responsibilities fill in practically entire of the fantabulous technique in lone fashion or distinctive, while QC is a subset of the QA hobbies. Also, constituents in the fantabulous technique might not be concretely substituted by QA/QC hobbies and responsibilities but perhaps enclose QA and QC. Quality control is a procedure which contemplates on performing the quality demand. Quality control intend to distinguish (and dead-on) imperfection in the finished product. Quality control, in consequence, is a reactive procedure. Quality control can be delineated as "section of quality management emphasized on furnishing quality must-have.

Application of statistical methods in the analysis of nonconformities of nonconforming products in the production process

Quality is the degree to which the totality of an object’s inherent characteristics meets the requirements. The product quality control system is a set of interrelated objects and subjects of control, the types, methods and means used to assess the quality of products. An effective control system allows you to make a timely impact on the level of product quality, prevent possible inconsistencies, and ensure their prompt detection at the lowest cost. One of the progressive methods in modern management is the statistical method.The article considers the program element for quality control in OJSC “BSW – Management Company of the Holding “BMC”. This program element is aimed at working with all types of nonconforming products of the enterprise, at finding the root cause and statistical analysis for these reasons.

Product Quality Control Analysis with Statistical Process Control (SPC) Method in Weaving Section (Case Study PT.I)

- PT.I is a company that produces synthetic rattan furniture on an export scale. The various products at PT.I are an attraction for consumers, such as classic and modern weaving models. However, the number of defects produced is higher than the tolerance limit company. Based on data from the weaving section, it shows that there are 5 types of defects that are not in accordance with the standards and quality that have been determined by the company. The purpose of this study is to identify the types of defects that often occur in PT. I and identify the main factors causing product defects using the SPC method. The seven tools consist of a check sheet, histogram, stratification, scatter diagram, p control chart, Pareto diagram, and fishbone diagram. The results showed that the number of defects in October and November exceeded the limit set by the company. The highest level of disability occurred in October. The higher the number of production, the higher the number of product defects. Based on the results of the p control chart, it can be seen that the product is outside the control limits that it should have. The process is in a state of uncontrollability or is still experiencing deviations. To suppress or reduce the number of product defects that occur in production, 3 types of dominant defects can be applied, namely the woven model (254 units), loose woven (122 units), and nail-looking woven (119 units). Factors causing defects in production are derived from human factors/workers, methods, materials/raw materials and work environment.
