How can you ensure your injection molded parts are safe to use?

1 Choose the right material

The first step to ensure your injection molded parts are safe to use is to choose the right material for your application. Different materials have different properties, such as strength, flexibility, durability, resistance, and biocompatibility. You need to consider factors such as the function, environment, and end-user of your parts, and select a material that meets the requirements and specifications. You also need to check the safety data sheets (SDS) of the materials, and follow the recommendations for handling, storage, and disposal.

4 Monitor and control your process

The fourth step to ensure your injection molded parts are safe to use is to monitor and control your process during production. Your process parameters, such as injection speed, injection pressure, cooling time, and cycle time, affect the quality and safety of your parts, so you need to keep them consistent and optimal. You can use various methods and tools, such as process control systems, statistical process control (SPC), and process capability analysis (PCA), to measure and analyze your process data, and identify and correct any deviations or variations.

5 Perform quality checks and tests

The fifth step to ensure your injection molded parts are safe to use is to perform quality checks and tests on your parts after production. You need to verify that your parts meet the specifications and standards for your application, and that they are free of defects, such as warping, cracking, flashing, or sink marks. You can use various methods and tools, such as visual inspection, dimensional inspection, functional testing, and performance testing, to evaluate and validate your parts. You can also use quality management systems, such as ISO 9001 and ISO 13485, to ensure your parts comply with the regulations and requirements for your industry and market.

6 Implement corrective and preventive actions

The sixth and final step to ensure your injection molded parts are safe to use is to implement corrective and preventive actions based on your quality checks and tests. You need to identify and eliminate the root causes of any defects or nonconformities, and prevent them from recurring in the future. You can use various methods and tools, such as root cause analysis (RCA), corrective action and preventive action (CAPA), and failure mode and effects analysis (FMEA), to analyze and improve your injection molding process and product. You can also use continuous improvement methods, such as lean manufacturing and Six Sigma, to enhance your efficiency and effectiveness in injection molding.
