Moulded Plastic Products

Dolphin Rubber supplies a comprehensive range of moulded plastic products to some of the world’s leading original equipment manufacturers. Many plastics suppliers specialize in just one type of moulding process, or offer a limited range of resins. This means their customers must maintain a large base of moulded plastic suppliers. It also means their customers’ design teams have to know which moulding process is best for any given design. At Dolphin Rubber, our designers work to develop the best, most effective product design for each application, regardless of material or moulding process. And our unique business model gives us the flexibility to produce component using right process & right materials at right price.

Dolphin Rubber Plastic Components Include
• Air Filters • Bellows • Brackets • Bushings • Caps & Tanks • Channels • Covers & Plugs • Ducts • Fill Tubes • Fittings • Fuel Filters • Handles • Hole Plugs • Impellers • Linkages & Levers • Oil Strainers • Plastic Fasteners • Spacers


Design

Utilizing solid modelling design software in conjunction with sophisticated analytical engineering tools such as our design engineering team collaborates with our customers to develop cost-effective solutions to their problems. In addition to extensive design and process analyses, we also conduct product validation tests to verify designs and ensure that our products will perform effectively in our customers’ applications.

Converting Metal Parts to Plastic

We have extensive experience with metal-to plastic conversions. Replacing metal with plastic can offer a number of advantages, including reduced weight, lower costs, and greater flexibility. Unlike metals, plastic materials can be easily configured to best suit a particular application. Plastics also allow for choices in moulding, making plastic more versatile than metal in many instances. Also, when designed properly, plastic parts can match or exceed the physical strength of metal.

Common Moulding Processes

Compression Moulding involves placing the uncured rubber compound into a heated, open mould cavity, then closing the mould under pressure (usually in a hydraulic press) to initiate vulcanization (curing). Transfer Moulding requires the uncured rubber compound to be placed in a transfer chamber, heated, then forced into the mould cavity under pressure until cured. Injection Moulding entails preheating uncured rubber in a chamber, then injecting it into a closed, heated mould.

Because transfer and injection moulds remain closed throughout the moulding process, they are generally capable of producing more intricate and consistent parts than compression moulds. Though they’re more expensive to produce, transfer and injection moulds also allow for higher temperatures, shorter cure times, and reduced finishing costs.

Formed Hoses

Dolphin Rubber is a major supplier of formed hoses to some of world’s leading original equipment manufacturers. Hoses may look simple, but there are many things to consider when designing hose for specific application. Our engineers work with our customers, & material development & quality teams to ensure that all hoses meet or exceed specifications.

Construction

Formed Hoses from Dolphin Rubber Include--• Air Conditioning • Air Induction • CARB-EPA • Fuel • Oil • Radiator (Coolant) • Steam • WateR

Formed hoses are generally composed of multiple layers. The innermost layer, or tube, is typically made of homogeneous rubber. The critical function of the tube is to chemically and thermally resist the media being conveyed. The tube may require fabric or wire reinforcement, which is the second layer of most hoses. The outermost layer is the cover. The cover’s main functions are to protect tube, provide reinforcement, & resist deterioration.

Materials

Material selection depends on the function of the hose. Dolphin Rubber can design custom hoses for specialized applications, or manufacture hoses to SAE J20 and J30 specifications. Materials commonly used in hose manufacturing include Ethylene- Propylene (EPDM), Fluoroelastomer (FKM), Nitrite (NBR), Chloroprene (CR), Epichlorohydrin (ECO), Chlorosulfonated Polyethylene (CSM) and Silicone (VMQ).

Manufacturing

A formed hose starts as an extruded tube. As the tube moves along a production line, reinforcement and additional rubber layers are added. The hose is then cut to length and fitted onto a mandrel that will dictate its final shape. The mandrel and hose are placed in an autoclave to cure the rubber. Once the rubber is cured, the hose is removed from the mandrel and trimmed to its final length.

Let Us Help

Dolphin Rubber designs and supplies a broad range of formed hoses. We also supply moulded and wrapped hoses. Our highly skilled engineering team will work with you to develop hose that fits your application & budget. Let us help you get the right hose for your next project.


Sealing Products

Dolphin Rubber has three decades of experience in every aspect of seal design and production. In fact, we supply a comprehensive range of sealing products to many of the world’s leading original equipment manufacturers. Our seal capabilities include time-tested designs as well as custom seals for any application.

Radial Lip Shaft Seals

Also known as oil seals, shaft seals are used with rotating, reciprocating & oscillating shafts to contain fluids & exclude contaminants. we offers a wide range of standard shaft seals, designs & develops custom seals for specialized applications. For more information see our comprehensive online reference book, Shaft Seal Design & Materials Guide.

O-Rings and Back Up Rings

We specialize in high performance O-ring materials such as Fluorocarbon (FKM) for high temperature and chemical resistance, Hydrogenated Nitrile (HNBR) for high temperature, abrasion and compression set resistance, and Polyurethane for abrasion and extrusion resistance. Back-up rings to prevent extrusion under extreme pressure and operating conditions are available in high modulus rubber, Polyurethane, Hytrel® and engineering plastics such as PTFE, PPS and PEEK. For more information see our complete online reference book, the O-Ring Design & Materials Guide.

Hydraulic Seals

We offer a complete line of hydraulic seals, including piston seals, rod seals, rod wipers, wear rings and buffer seals.

Lathe-Cut Seals

Lathe-cut seals are economical square or rectangular cross-section seals used in a variety of applications, including static seals and drive belts. Lathe-cut seals are available in diameters ranging from 0.25 in. (6 mm) to 7 in. (178 mm).

Gaskets

We offer a full range of die-cut, moulded and composite gaskets utilizing a wide variety of materials, including flexible graphite, PTFE, non-asbestos sheeting, cork, fibres, and metal, with or without pressure sensitive adhesive.

Let Us Help

We also offer an unlimited variety of custom-designed seals. Our highly skilled engineering team will work with you to develop just the right seals for your applications and budget. Let us help you get the right sealing product for your next project.


Custom Molded Plastic Products

A wide range of plastics make up a wide range of products.
Moulding Solutions has the capability of manufacturing all types of injection moulded plastic products. The niche in which Moulding Solutions has excelled is in those special plastic products that demand special attention or unusual techniques to mould.
An example of special processes are products in "rubber-like" materials (TPR, TPE or TPU materials). Common injection moulding technology assumes a rigid product, so these materials require special techniques to mould effectively.
Other plastic products that we have successfully manufactured involved special cooling fixtures, ultrasonic welding, unusual process controls or secondary operations.
