Silicone molding - Import export

The use of silicone in products has many advantages: the material is elastic, durable, and resistant to chemicals and high temperatures. As a result, the injection moulding of silicone has many applications, for instance in the medical world. For the injection moulding of silicone we are able to employ machines with a clamping force of between 25 and 100 tons. In this way we can produce units of less than a gram up to about 100 grams, varying in hardness from 10 Shore A up to about 80 Shore A.

Liquid Silicone Rubber (LSR) is a liquid silicon material, which is processed with an injection moulding process. Thanks to its special materials and processing properties, LSR offers unique design and production opportunities for Enbi Plastics. LSR has numerous uses in different industries, including health care, food, automotive, household appliances, and other sectors. For the injection moulding of silicon, Enbi Plastics uses machines with a closing force between 25 and 110 tons. This way we produce products made of components weighing from less than a single gram to approximately 100 grams, and which vary between <10 Shore A to approximately 80 Shore A in hardness, using both 1K and 2K injection moulding processes. Would you like to know more about LSR and how it can benefit your products or components? Our experts at Enbi Plastics love to help you with all your questions about LSR.

Creating an optimal bond between a metal plate and the silicone: that was the challenge Enbi Plastics was given by Océ Technologies, a major player in printing and copying equipment. They needed a new wiper assy; a part on the print head that prevents streaks on the paper. Because this part needs to be somewhat flexible, silicone needed to be added to a small, punched metal plate, to which screw thread is welded. This construction did not allow for a mechanical bond between the metal and silicone, which meant chemical bonding was the only option. Together with the client, the mould supplier, the silicone supplier and others, we did extensive research into the best way to achieve this bond. It showed that preparing the small metal plates was the key. After several tests, we discovered the optimal way to do this. A number of factors play a role: from how to clean and sand the plate to humidity, temperature and the time in between the steps of the process. Every detail counts!
