Pacorr Testing Instruments

 In the plastic and polymer manufacturing industry, consistency and accuracy are essential for producing high-quality products. One of the most important parameters used to evaluate thermoplastic materials is the Melt Flow Index (MFI) . It provides critical information about how a polymer flows under specific temperature and load conditions, directly influencing processing behavior and final product performance. To measure this parameter with precision and reliability, manufacturers rely on advanced instruments such as the Melt Flow Index Tester – Digital Model from Pacorr . This article discusses the importance of melt flow index testing, the working principle of a digital MFI tester, its key features, applications, and the benefits it offers to modern polymer industries. What Is Melt Flow Index (MFI)? The Melt Flow Index, also referred to as Melt Flow Rate (MFR), measures the amount of molten polymer that flows through a standardized die under a specified temperature and load w...

  Introduction In today’s competitive market, packaging is more than just protection—it is a reflection of brand quality and reliability. Customers expect products to arrive safely, without damage, and in perfect condition. One damaged package can affect customer trust, brand reputation, and repeat business. This is why packaging strength has become a critical part of both quality control and marketing strategy. A Box Compression Tester helps manufacturers ensure that their corrugated boxes can withstand stacking, storage, and transportation pressure. By investing in proper compression testing, companies not only improve product safety but also strengthen their market credibility. Why Packaging Strength Matters in Marketing Strong packaging directly supports brand promise. When products reach customers without damage, it builds confidence and trust. On the other hand, weak packaging leads to complaints, returns, negative reviews, and loss of customer loyalty. Box compression t...

 Corrosion is a persistent challenge for industries that work with metals and surface-coated components. Exposure to moisture, salt, and environmental contaminants can weaken materials over time, leading to reduced performance, poor appearance, and unexpected failures. To evaluate and control these risks, manufacturers use Salt Spray Chamber and Fog testing , an accelerated and reliable method for assessing corrosion resistance under controlled conditions. What Is Salt Spray Chamber and Fog Testing? Salt Spray Chamber and Fog testing is a laboratory-based corrosion testing process designed to simulate harsh environmental exposure. In this method, a fine mist of salt solution is generated inside a closed chamber. This salt fog settles evenly on test specimens, accelerating the corrosion process and allowing engineers to observe material behavior within a short testing period. Unlike natural exposure testing, which can take months or years, salt spray testing delivers results in da...

  Introduction Paper cores are a critical supporting component in industries such as packaging, flexible films, textiles, paper manufacturing, laminates, and adhesive tapes. These cylindrical cores carry heavy wound materials and are exposed to continuous vertical pressure during winding, stacking, storage, and transportation. Even a small reduction in core strength can result in roll collapse, material damage, operational delays, and increased costs. To prevent such failures, manufacturers use a Core Compression Tester , a specialized testing instrument designed to measure the axial compression strength of paper cores . This test helps ensure that paper cores are capable of withstanding real working loads without deformation. Pacorr offers advanced Core Compression Testers that support accurate testing and reliable quality control. What is a Core Compression Tester? A Core Compression Tester is a precision testing machine used to evaluate how much vertical load a paper core can...

  In today’s fast-paced manufacturing and logistics environment, ensuring that products reach customers without damage is a top priority. During storage, handling, and transportation, packages are often exposed to accidental drops and impacts. These incidents can compromise product quality, increase return rates, and negatively affect brand reputation. To minimize such risks, manufacturers depend on reliable testing equipment such as the Drop Tester (Motorized and Pneumatic) . At Pacorr , advanced drop testing solutions are developed to help industries evaluate packaging strength and product resistance under realistic handling conditions. This article discusses the concept of drop testing, the role of motorized and pneumatic drop testers, their working principles, applications, and benefits for quality assurance. What is Drop Testing? Drop testing is a controlled evaluation method used to determine how well a product or its packaging can withstand free-fall impacts from specific ...

  By Pacorr In industries where product performance and safety are critical, testing the mechanical strength of materials is an essential part of quality control. Materials such as plastics, rubber, metals, textiles, and packaging components must withstand various stresses during manufacturing, transportation, and end use. A Digital Tensile Testing Machine is a highly accurate and efficient instrument used to evaluate these strength characteristics, helping manufacturers ensure consistent quality and compliance with global standards. Introduction to Digital Tensile Testing Machines A Digital Tensile Testing Machine is designed to measure key tensile properties of materials, including tensile strength, elongation, yield strength, and breaking point. Tensile testing reveals how a material behaves when subjected to a pulling force, providing valuable insights into its durability and performance. With digital technology, these machines offer superior accuracy, automated testing, an...
