A sink mark is a phenomenon in which the surface of a molded product is slightly concave due to shrinkage. Molded products with external surfaces may result in poor quality. Sink marks may not appear on the surface of the part, and bubbles (cavities) may form inside the part. This is called a void. This phenomenon occurs because molten plastic resin for both sink marks and voids causes abnormal shrinkage in the process of cooling and solidification. Here, we will introduce tips for mold design to reduce the occurrence of sink marks, as well as challenges and solutions for measuri......

Compared to metal and ceramics, resin molding makes it possible to produce a large number of high-precision products at low cost. In addition, since it is cheaper and superior in mass production than processing methods such as cutting and pressing, there are many cases where parts that used aluminum etc. at the prototype stage are changed to resin at the mass production stage. However, it also has characteristics such as injection and blow failures due to abnormalities such as viscosity, temperature, and pressure during molding, and shape defects due to mold wear. Furthermore, du......

There is a tremendous need for high-quality translation in the biological sciences. Although it may seem dramatic, having a properly translated user handbook, electronic device instructions, or other medical documentation can ensure that the product is used in a safe and effective manner. Conversely, poor life science translation has been linked to 483 high-risk occurrences and product recalls, some of which have resulted in death. In such case, what steps can you take to safeguard your business relationships with translation se......

The product’s quality is its lifeblood. Improving the company’s reputation may be accomplished via the promotion of scientific management of the quality system. Improving a company’s fundamental competitiveness has far-reaching effects. Unfortunately, quality system management still has a long way to go. There are a number of issues with quality control management, including a lack of a comprehensive standard, an ineffective process for overseeing implementation, and a general lack of expertise. Because of this,......

There is no room for error in the industrial industry. A company’s success hinges on its ability to provide high-quality goods that either match or surpass consumer expectations. Companies that care about producing high-quality goods must devote resources to ensuring the quality of their output, assessing the effectiveness of current processes, and developing new ways to make those processes even better. Statistical process control is one method available to businesses for ensuring that quality control requirements are sati......

To put it simply, a quality control system is essential to the smooth operation of any firm. A quality control procedure may be developed by following these 6 steps: How To Set Up Quality Assurance Procedures? Prioritize quality over quantity Industry groups, municipal health and safety authorities, and even government agencies all have the power to establish quality standards for their respective fields. In other contexts, you’ll have to create your own quality standards since none exist at the institutional level. Di......

The measurement of workpiece size plays an important role in the industrial production, processing and manufacturing process. It is not only related to the production cost and quality of products, but also related to the use safety of products. As a typical representative of geometric measurement, thickness measurement has attracted much attention in the industry, and the automatic measurement of light transmitting and absorbing materials such as glass and black rubber plate is one of the difficulties in the industry. ......

What is important in blowing molding quality control? The equipment matters a lot for production, and the quality will be affected by many factors. Today, let’s learn about some common blow molding materials and how to improve the quality of blow molded products. Tips for Improving Quality of Blow Molded Products 1) Blowing pressureThe blowing pressure can make the semi-molten tube blank blow and close to the mold cavity wall to form the desired shape, and also can cool the blow molded products. Generally, too large or too small blowing pressure of a large volume is not conduciv......
