Precision, Consistency, and Continuous
Improvement in Every Part We Make
At Hoffer Plastics, quality isn’t just a department. It’s our promise. For three generations, we’ve built our reputation on delivering plastic parts that meet the highest standards of accuracy, consistency and performance. From design through production, our quality management system (QMS) ensures that every step of the process supports one outcome: confidence in the products we deliver to our customers.
Certified Quality Management System
More than parts quality – it’s business quality.
Quality at Hoffer Plastics goes beyond the product. It extends into how we run our business, manage risk and support customers. That’s why we maintain ISO 9001:2015 and IATF 1949:2016 certifications, verified through rigorous annual audits of our quality management system (QMS). These audits ensure that our processes align with internationally recognized standards, confirming our culture of continuous improvement.
Quality certifications are more than certificates on the wall. They’re a framework for accountability and a foundation for customer trust. By embedding this system into our daily operations, we consistently deliver unrivaled reliability, efficiency and customer satisfaction.
Materials & Equipment Matter
Quality parts start with quality materials and equipment. Hoffer continually invests in new injection molding machines, auxiliary equipment and process technologies to meet evolving customer demands.
Just as critical is material expertise. We work with customers to identify the right resin for each application, balancing performance, sustainability and cost efficiency. By matching world-class equipment with the right materials, we produce parts that not only meet but exceed expectations.
Mold Qualification & Part Validation
Before any part moves into full production, it undergoes a rigorous qualification and validation process. We follow customer-specific requirements as well as industry standards such as FDA, PPAP and FAI protocols.
This process includes extensive part inspections, process sampling and equipment validation. If needed, molds are refined or returned for modification to guarantee long-term robustness. Our precision measurement capabilities include tools such as:
Continuous Improvement Culture
At Hoffer Plastics, quality is not a checkpoint. It’s a mindset. Every employee is expected to stand behind our commitment to excellence, and continuous improvement is embedded into our business model.
We invest in Lean manufacturing, 5-S workplace organization and Six Sigma-trained employees to drive efficiency and eliminate waste. Our proactive philosophy means we don’t wait for problems. We prevent them through structured processes like:
- New project risk assessments.
- Quality assurance (QA) and quality control (QC).
- Advanced Product Quality Planning (APQP).
- Process optimization and validation.
- Statistical process control (SPC).
- Root cause and corrective action plans.
- Internal auditing and compliance reviews.
This systematic approach ensures smoother launches, faster cycles, fewer defects and more reliable outcomes.
Beyond Compliance: A Promise of Excellence
While certifications and audits provide structure, what sets Hoffer Plastics apart is our relentless focus on the customer. Quality is not a box we check; it’s a culture of accountability, precision and service that permeates every project.
We know that our parts often play critical roles – in medical devices, automotive components, food packaging, and countless other applications. That’s why our quality standards are designed to protect not just parts, but people, performance and reputation.
A culture of quality drives everything we do at Hoffer. Every employee shares responsibility for building quality into each part, process and customer relationship to ensure precision, reliability and results our partners can count on for generations.
