Continuous Molding The proprietary moulding method typically results in nearly the same quality as traditional fully moulded techniques with almost undetectable joints. Investing in continuously moulded methods will increase the consistency of higher-performance sealing applications. The best option for large and critical applications like in Vacuum, LCD, and Solar equipment manufacturing with low seal compression force. Possible slight parting line and flash misalignment and variable surface finish at the mould transfer points. ID dimensional tolerances per quote. | |
Serpentine Fully Molded Traditional fully moulded techniques are performed with non-traditional gland configuration. Glands are typically snake shaped to allow more linear space. Besides the high mould cost, the main disadvantage is the seal can relax in the shape of the mould which makes installation more challenging and increases the potential for leaking. Compression moulding parting line and flash may also be an issue since typically hand trimmed due to the overall size. The continuous Molding method has replaced this method in most situations. | |
Moulded Joint The partially cured moulded cord is joined and moulded under pressure and high temperature in a tool/fixture. Depending on size multiple joints could be used. The finished seal is then placed in a high-temperature post-cure oven to complete the cure. After the o-ring is fully cured, it is de-flashed and buffed if required. ID dimensional tolerances per quote.

Precision Spliced and Vulcanized The fully cured extruded cord is typically cut to length with a 45-degree angle scarf cut ends. A proprietary process is performed to bond the ends with a rubber and adhesive mixture that results in a much cleaner joint than Standard methods. The consistently cleaner joint allows for better sealing with less leak potential which can be used in higher-performance applications. The good joint tensile strength can be achieved with Buna-N, Neoprene and EPDM, reasonably good with and only fair strength can be expected with Silicone. Great for prototyping before migrating to the Continuous Molding method. ID dimensional tolerances per RMA Table 18, S1 Precision or better.

The fully cured extruded cord is typically cut to length with a straight 90-degree or 45-degree angle scarf cut ends depending on the material type and thickness. The ends are treated with a mixture of uncured rubber and adhesive and placed in a tool fixture to heat and cure the joint. Once removed from the fixture the joint might be buffed but imperfections could remain that can cause leaking in some applications thus recommended for very basic short-term non-critical applications. Joint quality can vary as they are produced by hand. The good joint tensile strength can be achieved with Buna-N, Neoprene and EPDM, reasonably good with and only fair strength can be expected with Silicone. ID dimensional tolerances per RMA Table 18, S2 Commercial or better.
