Injection Moulding
  • Excellent technical support. We involve them at an early stage and allow them to provide solutions to problems.

    We have worked with captive closures for over 5 years now. Historically development of new products can be a lengthy as well as a costly process. However due to their dynamic approach to problem solving, enormous experience of polymer engineering and their ability to transform concepts into working prototypes we have been successful in developing many products like our globally famous nail gripper. Through their almost unique service we have consistently managed to keep development budgets tight, and more importantly, cut the time to market of several new products, Captive Closures are a company that goes that extra mile. Their service and communications are second to none.

    Captive Closure are a superb example of a clean and modern Injection Moulding facility and coupled with their documented quality procedures, team working philosophy and guaranteed lead times, they are consistently able to offer complete satisfaction.

    Heritage Dove Packaging are involved in the supply of packaging products to many High Street retailers but due to the nature of the business, we are constantly under threat from cheaper foreign imports. Our long association with Captive Closures has been instrumental in allowing us to combat much of this competition and successfully retain, and increase our market share. They are a superb example of a clean and modern Injection Moulding facility and coupled with their Documented Quality Procedures, Team Working Philosophy and Guaranteed lead times, they are consistently able to offer complete satisfaction. We at Heritage Dove are extremely proud of our reputation within the industry and look forward to a continued working 'partnership' with Captive Closures together with the associated benefits this brings. From our experience, I would have no hesitation in recommending them to others.
