A Plastics Quality Inspector is a professional who is responsible for ensuring the quality of plastics used in industrial and commercial products. They inspect raw material and finished products for any defects or flaws, including any irregularities in texture, color, shape, size and strength. They may use various tools such as calipers, microscopes, laser scanners and other testing equipment to measure and identify defects.

The results of their inspections are used to determine the quality of the product, and if necessary, corrective action can be taken to avoid future problems. The overall goal of the Plastics Quality Inspector is to ensure the highest possible quality of products and to protect the health and safety of consumers.

Steps How to Become

Earn a High School Diploma or GED. Most employers require plastics quality inspectors to have at least a high school diploma or GED before they will be considered for hire. It is essential to complete this requirement in order to qualify for a job as a plastics quality inspector.
Pursue Technical Training. While a high school diploma or GED is necessary, employers may prefer applicants who have completed some type of technical training. Most commonly, an associate degree in plastics technology is preferred. Through these programs, individuals can gain an understanding of engineering principles, plastic fabrication and manufacturing processes, statistical process control and quality assurance systems.
Obtain a Certification. Obtaining a certification in plastics technology can be beneficial in order to stand out from the competition. There are several certifications that can be earned through independent organizations, such as the Society of Plastics Engineers and the American Society for Quality.
Find a Job. Once these steps have been completed, individuals can begin searching for jobs as plastics quality inspectors. Many plastics companies hire for these positions, as well as manufacturing companies and industrial supply companies. Job seekers should search these types of companies in order to find job openings.
Build Experience. Although experience is not always required for entry-level positions, it can certainly make an individual more competitive when applying for a job. Candidates should look for opportunities to gain experience in the plastics industry through internships, volunteer work or part-time positions. This can help them to build their knowledge and skills in the field, making them more attractive to potential employers.

The quality of plastics is a critical factor in their production, as it can have a significant effect on their performance, durability and safety. Poor quality plastics can lead to product failure and even cause injuries if they are used in certain applications. As such, it is important to have a qualified and experienced plastics quality inspector on hand to ensure that all plastics meet industry standards.

A plastics quality inspector has the skills and knowledge to identify any problems with the material, whether it is a structural issue or something more subtle. They can then take corrective action to ensure the plastic meets the necessary standards and is safe for use. By having a qualified plastics quality inspector on staff, manufacturers can be confident that the materials they are using are of the highest quality, reducing the risk of product failure and helping to ensure the safety of end-users.
