Silicone rubber keypads are widely used in various electronic devices. Choosing a right silicone rubber keypad supplier is crucial to ensure that you receive high-quality and reliable products. In this article, we will discuss the two types of silicone rubber, and the four key points to consider when selecting the correct silicone rubber keypad supplier. 

Material, there are two types of silicone rubber

Solid silicone rubber: 

It's a semi-transparent solid material that is typically referred to as "raw material" before the mixing process. The final product's hardness and color are determined during the mixing process. Solid silicone rubber is currently the most commonly used material for silicone rubber products. The molding process involves dividing the mixed raw material into portions according to the product's structure, size, and weight. The silicone rubber semi-finished products are then placed in an open and close mold, heated, and then molded into the desired product shape. 

Solid silicone rubber is non-toxic, odorless, and tasteless, making it ideal for use in food, medical, and other sensitive industries. Additionally, it has good electrical insulation properties, making it ideal for use in electronic products.It is a widely used material for producing silicone rubber products. Its molding process is efficient and cost-effective, making it a popular choice in many industries. 

Liquid silicone rubber (LSR): 

LSR is a two-part material that is mixed and injected into a mold to form a part. It offers excellent precision and is a popular choice for complex parts. The molding process for LSR involves directly feeding the A/B liquid silicone rubber raw materials into a liquid injection molding machine. Automated equipment is then used to accurately feed and inject the material to produce the desired product.LSR injection molding is primarily used for high-precision products such as those with strict burr control or high transparency appearance for medical-grade human contact products. However, due to the high cost, LSR injection molding is not as commonly used as solid silicone rubber molding.

LSR is a high-transparent liquid material that offers excellent properties, making it suitable for a range of applications such as medical and electronic devices. LSR injection molding is a precise process that requires advanced equipment, resulting in higher production costs. 

Four Key Points to Consider:

1.Quality Control:

Quality is a crucial factor in selecting a silicone rubber keypad supplier. A good supplier should have strict quality control measures in place to ensure that the final product meets the required specifications. The supplier should conduct regular inspections of the raw materials, production process, and finished products to ensure that they meet the desired standards.

2.Technical Expertise: 

The supplier's technical expertise is another important consideration. The supplier should have experienced engineers who can provide technical assistance to ensure that the design and production of the silicone rubber keypads meet the desired specifications. They should also have the capability to provide custom designs and sizes to meet specific customer requirements.

3.Production Capacity: 

The supplier's production capacity is another critical factor. It should have the necessary machinery and equipment to produce silicone rubber keypads in large quantities, without compromising on quality. It is also important to consider the lead time for production and delivery, as this can impact the overall timeline of your project.

4.Customer Service: 

The supplier's customer service is the final point to consider. The supplier should have a responsive and helpful customer service team that can assist you with any queries or concerns. They should also be able to provide timely updates on your order status and delivery.

The current situation of silicone rubber keypad factories

Currently, many silicone processing factories operate as single-production facilities, lacking comprehensive facilities for producing a complete silicone product. For example, product printing, spraying, and surface treatment all require outsourcing, and the lack of process integration and overall production capacity often fails to meet the requirements of larger companies, making it difficult for quality-conscious investors to find suitable factories. Very few factories have integrated facilities for mold making, solid processing, liquid processing, spraying, printing, laser engraving, sewing, and assembly. The main reasons for this are cost control and process deficiencies. Factories with such comprehensive facilities often have high entry requirements, making it difficult to find a fully integrated silicone processing factory that meets all requirements. 

However, with over 30 years of experience in silicone product OEM manufacturing, JOESMEN continuously invest in the latest equipment and technology to expand our production capacity. We assign dedicated personnel to participate in various equipment and process innovation exhibitions, without limiting ourselves, and setting higher goals and challenges for ourselves while pursuing stability for our clients. We are JOESMEN, your reliable partner for silicone OEM manufacturing. 


Choosing the correct silicone rubber keypad supplier is essential to ensure that you receive high-quality and reliable products that meet your specifications. When choosing a supplier, consider the quality control measures, technical expertise, production capacity, and customer service. By taking these factors into account, you can make an informed decision and select a supplier that will meet your needs and expectations.
