What is Dip Molding

Dip molding is a versatile manufacturing process that uses a mold to create products with a hollow interior. Dip molded parts are ideal for a wide range of applications, including many products used in the medical and surgical industry, and they offer several benefits.

Process Details

To produce high-quality dip molded products, KEP completes a series of steps to ensure proper formation, vulcanization, and finishing for the product.

Manufacturing dip molded products involves 5 main steps:

  1. Coagulant Dipping
  2. (Natural or Synthetic) Rubber Dipping
  3. Leach Dipping
  4. Cure or Vulcanization 
  5. Finish

Materials & Applications

KEP offers a specialty line of latex and non-latex compounds for our customers to choose from when manufacturing dip molded parts, including natural rubber latex, neoprene and synthetic polyisoprene. Common applications are detailed below. Learn more about the specific benefits of these materials by following the links for each.

Natural rubber latex offers the best elasticity and barrier protection for the lowest cost. Although KEP’s natural rubber latex products do not have detectable levels of proteins, there is a nonzero risk of an allergic reaction. Because of this, natural rubber latex is ideal for dip molding applications where latex allergies are of little or no concern. Common dip-molded products made from natural rubber latex include radiation attenuation gloves, radiopaque Penrose drains, urine bags, finger cots, catheter balloons, ultrasound probe covers, and other device covers. 

Neoprene compounds offer excellent durability in harsh conditions and are latex allergen-free. Neoprene rubber features resistance to flames, oil (moderate), weather, ozone cracking, and abrasion and flex cracking, alkalis and acids. This material is commonly used for dip-molded products such as surgical bellows, catheter balloons, ultrasound probe covers, and other types of device covers.

Synthetic polyisoprene offers similar feel and elasticity to natural rubber latex, but without the potential for Type I latex allergy reactions which makes it a safe replacement for hard rubber. Common uses for synthetic polyisoprene for dip molding are similar to the ones mentioned above, finger cots, catheter balloons, ultrasound probe covers, and other device covers.

Benefits of Dip Molding

Whether you need products for a brand-new startup or a large multinational corporation, choosing dip molding for your manufacturing process can offer you several benefits. KEP ensures high quality and consistency for our dip molded parts and products, manufacturing products that a wide range of industries rely on and trust. Ideal for rapidly manufacturing products at the scale you need, large or small, choosing dip molding is also a cost-effective manufacturing solution.

Custom Dip & Prototypes

At KEP we have over 60 years of experience in dip molding, which includes both automated continuous-dipping and semi-automated batch-dipping processes. We’re based entirely in northeast Ohio, with our latex dipping operation just outside of Akron (known as the Rubber Capital of the World). We run a custom batch dipping operation which allows us to produce small batches of niche products and prototypes to exact specifications for our customers, but we’re also able to scale up our operations. 

KEP Dip Molding

KEP follows cGMP and uses its ISO 13485:2016 quality management system to ensure total quality for all our products. Our raw materials, production machinery, and gauges are all strictly tested, monitored, calibrated, and maintained at every step of the manufacturing process. We also ensure our dip molded parts meet FDA guidelines and requirements set by the FDA for Medical Devices.
