Quality Inspection for Plastic Components to Drive Business

The use of plastic components for manufacturing products is increasing with each year. It is a cost-effective replacement for components like metal, glass, and wood. From textile to food packaging, plastic components are used in a wide array of industries. Global demand for construction is also one of the major reasons for driving the revenue of plastic industry.  According to Statista, China is the largest producers of plastics in the world and it is known to import high-quality plastics to the United States over the ages. The reason behind this is its focus on the quality control.

The production of plastics starts from obtaining the raw materials, synthesizing polymer, blending the polymer into a usable fraction, and end the process with the shaping and structuring.  All these processes need to undergo a series of meticulous vetting for delivering excellent products. Here’s how the inspection companies conduct an inspection of the plastic components:

Raw materials examination: After the raw materials are obtained for production, the resins and fiber are examined based on several factors including viscosity, moisture, color, durability. These processes are important to determine the average weight of the components.

Identification of internal defects: This inspection process involves the use of ultrasonic waves which helps to identify the internal defects, voids, or contamination of foreign elements. It is also important to detect if there is any insufficiency in the lamination process. If these defects can be detected in the initial stages then it helps to prevent high rejection rates and cost overruns later on.

Check fiber distribution: This usually involves radiographic inspection which is important to identify large voids, translaminar fractures, distribution and patterns of the fiber, etc.

Temperature regulation: With the aid of infrared measurement process, the surface of component comes up with the defects and cracks and this is necessary to regulate film temperature of the plastic component is regulated for a smoother layering.

Acoustic inspection: This process involves microscopic cracking, fiber detachment, fiber breakage, and local delamination. This is important to identify the defects in the molded products.

Outer defect inspection: This is one of the most important quality inspection processes. This inspection involves checking the visual appearance of the end products.This identifies defects like sink marks, burn marks, short shots, flow marks, bubbles, flash marks, etc.

Adherence to AQL: It is only with the help of professional quality inspection, you can get the assurance that products adhere to standards of Acceptable Quality Limit (AQL).

Functionality Testing: The final products are tested with the help of technological tools and human effort to check the functionalities.
