Quality Ensured Plastic Products

Another aspect that sets Inplex apart, aside from our diverse capabilities and customer service, is the extreme commitment we have to quality products.

At Inplex our commitment to quality is unmatched. Our team has multiple certifications, qualifications, and processes to ensure the level of quality for our customers.

Inplex ISO 9001:2015 Certification

Inplex once again received an International Organization for Standardization (ISO) 9001:2015 audit of our quality management system. The ISO is an internationally recognized standard for quality management.

For the ninth consecutive year, Inplex fulfilled the requirements and received re-certification, with zero minor and zero major non-conformances. This audit included areas such as sales and order entry, production, calibration, production equipment, and purchasing. Each area was audited and re-certified by an independent auditor. Our years of certification demonstrate that Inplex is a well-established manufacturer with reliable and consistent standards in their custom plastic products.

Inplex’s IMS Certification

Inplex also boasts Integrated Management System (IMS) certification.

Our IMS integrates all of our processes and systems into one framework, enabling us to work as a single unit with unified goals. Accordingly, we apply quality management standards during every stage of the manufacturing process. This provides several benefits, including high production quality, minimal downtime, faster time-to-market (TTM), and improved customer experience.

In contrast, non-IMS organizations focus on management systems individually. Quality assurance is typically delegated to a quality team that only implements quality control after specific manufacturing stages. This can result in oversight, miscommunication, and longer downtime.

Other Quality Control Measures

At our facilities, Inplex also uses the Admet eXpert 7601, Non-contact laser micrometers, and QDA 9 Datamyte to ensure the quality of our products. Learn more about how we ensure quality in our recent blog, Quality Assurance for the Best Plastic Extrusion Products.
