Molding Processes

MOCAP offers more because we own and operate multiple manufacturing facilities which specialize in several manufacturing processes. They are as follows:


Vinyl (PVC) Dip Molding

MOCAP's Vinyl Dip Molding capabilities are second-to-none. We stock a wide range of plastisol PVC materials used to make the flexible vinyl plastic caps, plugs, handle grips and masking products you need. If your product or project requires a dip molded part in a special color, hardness or texture, we can deliver. Size is rarely a concern as we can produce dip molded parts as large as 18" diameter, and from 0.062" to over 22" long. Of course every process has its limitations, so please Contact MOCAP to discuss your specific custom project.

The most common dip molded items MOCAP produces are traditional round vinyl caps and round vinyl handle grips, however MOCAP is also the industry leader at producing low-cost high-quality custom dip molded products.

Dip Molding Explained
The dip molding process involves sets of identical molds pre-heated then simultaneously lowered or "dipped" into a pool of liquid plastisol PVC vinyl material. The molds are held in the liquid material at the desired depth for a specific period of time to ensure the correct amount of material clings to the mold. The molds are then lifted out of the liquid material and transported through an oven where the liquid plastic material is baked/cured into the desired part. The parts and molds are then cooled to a temperature which allows the parts to be stripped from the molds at the end of the process. The cycle repeats until the desired quantity of parts has been made.



Plastic Injection Molding

The Plastic Injection Molding process produces the most consistent and cost-effective parts from commercial grade thermoplastic resins. Plastic Injection Molding can produce plastic parts to tight tolerances and demanding specifications. MOCAP continues to satisfy your needs by providing custom plastic injection molding for more choices of caps, plugs, grips and other plastic products by expanding the sizes, shapes and types of plastic injection molded products we manufacture and stock.



Thermoset Rubber Injection and Compression Molding

MOCAP EPDM and Silicone Rubber products are made using state of the art rubber injection or rubber compression molding processes. Rubber molding differs from plastic injection molding in that rubber products are "themo-set", meaning the raw material is cured or hardened when heat is applied. The raw material is injected into the mold cavities under pressure and when heat is applied to the mold and held for a period of time, the material cures or "sets" into the shape of the cavity. When the mold is opened, the resulting parts are removed and the cycle repeats. MOCAP offers years of experience in rubber molding including processing a wide range of thermoset rubber materials like Silicone, EPDM, Neoprene, SBR, and Viton®.



Plastic Extrusion

MOCAP manufactures a full line of semi-rigid clear extruded plastic tubes commonly used to package products in a unique, highly visible manner. Produced in a wide assortment of sizes, styles, wall thicknesses and lengths, our packaging tubes are ideal for use in many different industries. Visit cleartecpackaging.com for more information.




Silicone Rubber Extrusion

We utilize the most advanced equipment and systems to produce extruded silicone rubber products including silicone tubing and X-Treme Tape™, our self-bonding silicone wrap which resists x-tremes in temperature, electricity, moisture, corrosion and contaminates.




Secondary Operations

When your application requires something more than a standard part, MOCAP offers several secondary operations to convert, enhance or improve your products.
  • Printing can add your logo or other valuable information to most vinyl dip molded caps, plugs and handle grips.
  • Slicing to remove a portion of the item to create a custom fit or function.
  • Slitting to add a slot or thin opening.
  • Punching to add a hole or customer shape not possible through typical molding processes.
  • Assembly to create products from components, or add a package to your product.
