In the 1960's, engineers developed a way to use the same principles in molding plastics to mold rubber, making rubber injection molding one of the most efficient rubber manufacturing processes. The rubber injection molding process works by significantly heating the rubber and using a very high pressure to inject the rubber compound in to the mold.
The amount of rubber that is injected into the mold using high pressure can be controlled exactly which leads to a more controllable production process. Highly efficient, short production cycles, constant and uniform temperature and pressure throughout the process.
Rubber injection molding successfully alters the plastics process by heating the rubber and placing it under significantly more pressure per square inch of cavity surface in molding. This is different from the plastic injection molding process where the materials are cooled under less pressure.
Sep 07, 2017 · The pressure range used for Liquid Silicone Rubber (LSR) is between 100 and 1000 bar, and the injection time is between 0.5 and 3.0 seconds to avoid premature curing of the material before the cavity is completely filled.

With the upsizing of ships and the needs of berthing docks, the ship’s fender equipment has gone through several stages, from the solid rubber fender made of brown rope to the floating inflatable rubber fender. Floating inflatable rubber fender has many advantages such as angular compression, high energy absorption, low pressure on hull and good motion with waves, so it is widely used.
After overcoming the initial issues of temperature, (plastics are cooled when molding and rubber is heated) and pressure (rubber injection molding requires significantly more pressure per square inch of cavity surface), the process has become an efficient way to mold rubber in many cases. There are 3 main types of rubber injection molding:
Oct 05, 2018 · An injection press holds the mold in place with immense pressure to keep the mold secured during the quick curing cycle. Finally, when the material cures, it’s removed from the mold, and the process quickly repeats. Rubber injection molding is the best solution for producing components with precision. Advantages of Injection Molding
Feb 24, 2015 · 4. Heat and pressure are applied to the LSR material until it is cured into a solid state. Once the cycle time is complete, the mold opens and a worker (or an automated process) removes the rubber part along with any flash. Subsequently, the mold closes again to repeat the same process. 5.
Apr 07, 2019 · 1,Plastic Injection Molding Pressure. This is the pressure caused by plastic flow, and can be measured with sensors on the nozzle or the hydraulic line. It does not have a fixed value. The more difficult it is to fill the mold, the higher the injection pressure is required. The linear pressure is directly related to injection pressure.

May 31, 2019 · Generally, rubber molding produces parts with longer cycle times–largely because of cure times and “blowing-off” the part (using air pressure to release it from the mold). This extra, more manual technique creates a difference in cycle time that can be as extreme as 5 plus minutes.
Feb 15, 2017 · Injection Pressure. This is the pressure that causes the material to flow, and it may be approximately measured by a transducer located in the hydraulic line or in the nozzle. It does not have a constant value but increases as mold filling becomes more complex. There is a direct relationship between injection pressure and injection line pressure.
