With the popularity of silicone foundry in Taiwan over the past ten years, silicone products have become inseparable from our lives. Because of the excellent heat resistance, water resistance, and chemical resistance of silicone rubber, it is widely used in various kitchenware and baking equipment; the good elasticity and ductility of silicone rubber also improve the life span of remote control buttons, automotive interior buttons and related accessories. Before choosing a silicone manufacturer, it should be noted that there are so many options on the market from a small workshop to a big factory. How should customers evaluate the suitability of those silicone manufacturers? Here are three key entry points to help you find the best silicone manufacturer.

The first thing to look at when evaluating a silicone manufacturer is the quality of the OEM capability. There are some differences in the molding method, mold design, and production equipment of different silicone products. How to choose an experienced silicone manufacturer? Check out the following methods:

Mold design can be said to be a key step in the entire silicone manufacturer OEM service, including designing molds, processing and producing molds, making samples, and modifying molds. This is usually a technique-consuming process. High-quality molds are the predecessor of high-quality products. Designing molds not only requires huge engineering knowledge but also the creativity that comes from profound experience. Therefore, asking "the seniority of the experience of doing silicone manufacturer OEM" and "Do they own a professional mold design department?" "Does it have its own laboratory for high-precision dimensional testing?" These are good questions to check the quality of mold design.
Whether it is a mixing machine for compound materials, a baking machine for post-curing materials, a hot-pressing machine and an injection machine for silicone rubber molding, a spraying cabinet for printing patterns, a pad printing machine, and a grinding machine for finishing products…, a finished product needs to be processed by a variety of equipment to complete, understanding the diversity and quantity of equipment can help you evaluate the capacity of silicone manufacturer and production technology reference.

With the relevant technology and equipment, if you want to know whether a silicone manufacturer is professional or not, you must look at the operator of the technology and equipment. A silicone manufacturer usually consists of a mold department that designs molds, an engineering department that tests molds, a production department that produces products, and a quality control department that checks the process. The more you inspect each link of the company, the less you will lose. Here we provide you with a simple way to judge whether the team is professional or not.

Questions from the production team of the silicone manufacturer are also clues for judging professionalism. At this time, you can refer to the company's official website or the common questions in the company's catalog to quickly clarify the advantages and capabilities of the production team. It is recommended to ask "How long does it take to make a mold?" Time?", "Can the product size and design be changed?", "What information should the customer provide?", confirming these questions are the key to saving a lot of time and money.

Compression molding and injection molding are the main methods of silicone molding used by a silicone manufacturer, but based on these two foundations, the most suitable method for this type of product can be extended according to the nature of the product.
The material is placed under the cutting area of the machine to cut the desired shape, which is called die cutting. This process is commonly used by a silicone manufacturer and is suitable for mass production of flat components, such as silicone film for remote controls or sticky self-adhesive paper.

Whether it is over-molding by hot compression molding technology or embedded injection by liquid injection molding technology, these two production procedures are used to coat metal or other solid materials with silicone rubber, such as tableware and toothbrushes with silicone rubber handles, and other products. As long as the solid material is put into the mold, and the solid material of the inner core is covered by the silicone rubber by molding or injection, it can be combined into one. Two dissimilar materials can be joined together without going through an adhesive, which is better than adhesive. At the same time, it saves processes, reduces manual assembly procedures, and improves production efficiency.

The technique of combining two different liquid materials in the injection cavity and forming the shape is called double injection. If the semi-finished products are made of silicone rubber, double-material injection will be the best solution, such as earphone sleeves, gasket seals, etc. Double-material injection also has the same advantages as overmolding and embedded injection, which can bring high quality to the product. Strong binding and reduce subsequent assembly procedures.

Take a multi-color silicone button as an example, the button and the rubber panel are first cut out by punching, and then the two are combined into one through the overmolding process. If you need a product that needs to go through more than two construction methods, it is highly recommended to find a one-stop company like Glory Sun that involves a few industries and has complete construction methods. On the one hand, it can reduce the conflict in design, and on the other hand, it can also ensure the consistency of the finished product. You can evaluate the demand for the product to find a suitable silicone manufacturer.
