How to choose silicone OEM manufacturer？
The most common method of silicone rubber molding
- The most common solid silicone rubber is used for this procedure. Compression molding is to mix and soften the solid silicone rubber of the raw material, and then put the silicone raw material into the mold to heat up and pressurize it. The advantage is that the cost and processing environment conditions are low. Compression molding is also the most common process in silicone rubber production. It is suitable for the production of products with a simple design appearance and larger dimensional tolerance and can meet the needs of mass production of components in the manufacturing industry.
- Liquid Injection MoldingUsing high-transparency, fluid-like liquid silicone rubber, inject the liquid silicone rubber into the closed mold, and heat it to solidify and form, the overall production process can maintain high cleanliness, high precision, and very little residual material, often used in production Precision optical products, and high-contact medical silicone products. Also because the silicone content, raw material cost, and development mold of injection molding are higher than those of compression molding, generally speaking, the production volume must be large enough to share the cost and reduce the unit price of the product. It is suitable for the automotive industry or the medical industry, etc., which have a large demand for precision components.

Mold design experience
Mold design can be said to be a key step in the entire silicone rubber 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 rubber 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.
Adequate production equipment
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 rubber manufacturers and production technology reference.（Extension Reading: 4 Tips for Choosing A Silicone Molding Companies ）
Professional silicone molding team
With the relevant technology and equipment, if you want to know whether a silicone rubber manufacturers is professional or not, you must look at the operator of the technology and equipment. A silicone rubber manufacturers 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.
- Seniority: The seniority of a silicone rubber manufacturers represents how long the company has lived in this market. The longer it lives, it means that it spans the challenges of various periods, has considerable flexibility, and is definitely superior in production expertise and efficiency. It is worth investigating.
- Professional field: silicone rubber manufacturers can be applied in a wide range, and each field has its unique needs. In order to meet different fields, the professional knowledge and equipment possessed by silicone rubber manufacturers are also classified into different categories. They understand which industries they focus on developing, and can deduce the equipment or any uniqueness that the company may have, such as those involved in the automobile and electronics industries. Enterprises that are good at designing products with high dimensional accuracy are likely to have professional detectors; those involved in the food and medical industries show that their equipment may be equipped with clean rooms, and raw materials that pass environmental testing requirements can provide highly clean products.

Questions from the production team 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.（Extension Reading: Enterprise core value ）
Compression molding and injection molding are the main methods of silicone molding, 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. Die cutting is suitable for mass production of flat components, such as: silicone film for remote control, or sticky self-adhesive paper .（Extension Reading: Die-cut | Adhesive Process ）
Over-molding / multi-component injection
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.（Extension Reading: Over-molding ）
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.（Extension Reading: LSR 2-Shot Injection ）
It should be noted that customers also need to know whether their silicone products need to go through multiple processes. 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 rubber manufacturers.（Extension Reading: LSR Single Shot Assembly ）
