Quality Control Solutions

Innovative Quality Control Services for Manufacturing Firms

The importance of diligent quality control in the production process cannot be overstated. Poor QC can lead to your company producing products of inconsistent quality. It can also result in a higher number of product defects. If your company’s products fail to live up to the expectations of your customers, or if there are significant differences in product quality from one order to the next, they will quickly become dissatisfied and begin searching for new providers. An experienced quality control solutions provider can help your team achieve peace of mind. If you’re searching for manufacturing quality control services, turn to Tengco.

For more than 40 years, we have collaborated with firms worldwide to ensure their products are of consistent quality, free of defects, and compliant with state and federal regulations.

Save Money. Satisfy Customers.

Quality control in manufacturing isn’t exclusively focused on minimizing product errors and maximizing consistency in quality from one item to another. It’s also about discovering more efficient designs for your existing products. At Tengco, we are constantly searching for new ways to improve your product’s performance and make your design work for you. Unlike many of our competitors, we have a team of engineers that can review your product designs and offer suggestions to improve their efficiency and save you money. If a problem arises, we can handle retooling on-site as well.

We also make the process of developing a product easy. When you need the design of a part altered, simply send us a sketch of the part and our team of engineers will take it from there. Throughout the process, our manufacturing quality control team will perform a range of tests, including dimensional and mechanical testing for tensile, proof load, and hardness. If they discover any defects, they will ensure each of them gets addressed before the parts are shipped. When you choose Tengco as your quality control solutions provider, you can feel confident your company will provide its customers with products of exceptional quality every time they place an order.
