Custom automotive silicone keypads

Yuanyi is a manufacturer specializing in automotive silicone keypads. Everything is completed in-house and strictly adheres to the quality management system from product design, rapid prototyping, mass production molds, molding, and post-processing to packaging. Automotive silicone keypads are commonly used silicone rubber products. They are usually made of high-temperature vulcanized silicone rubber (HTV) through silicone compression molding, edge removal, silk screen printing, fuel injection, laser engraving, and other processes. Liquid silicone rubber is sometimes used and is molded by injection injection molding according to design requirements or personal customization. Silicone rubber has good resilience and temperature resistance, while thermoplastic resin has high rigidity and wear resistance. Some automotive silicone keypads are made from a combination of silicone rubber and thermoplastic resin, which combine the properties of the two materials to give them a better feel, durability, and stability. Some automotive silicone keypads are made from a combination of silicone rubber and thermoplastic resin, which combine the properties of the two materials to give them a better feel, durability, and stability

Due to silicone keypads being waterproof, smooth, and wear-resistant, they are usually used in multi-function steering wheels, instrument panels, and control panels. In the design and manufacturing process of automotive silicone keypads, engineers take advantage of the characteristics of different manufacturing materials and product functional requirements, combining silicone rubber parts and thermoplastic resin parts, which are treated with surface processes, to achieve better product performance and user experience.

Characteristics of automotive silicone keypads

Odorless, non-toxic, and corrosion-resistant.

It has the characteristics of excellent resilience and soft touch and can be used for a long time even at 200℃ or still elastic at -60℃.

With excellent heat and cold resistance, the operating temperature range is -55℃ to 250℃.

It has superior resistance to ultraviolet rays, ozone, moisture, salt spray, mold, etc., allowing it to be used more than 20 years for outdoors without cracking.

Excellent resistance to chemicals and oils, so it will not corrode the casing and internal circuit boards during use.

The unique surface treatment prevents the text of the key from falling off or fading.

Automotive silicone keypad custom process

First, communicate with the customer about detailed customization requirements and confirm drawings. If the customer provides a sample, the drawings can be designed and confirmed based on the physical data, and then the sample can be produced. This process generally takes 3-5 days.

Batch mold manufacturing begins after the sample passes the customer's final test. Depending on the dimensions of the mold and the complexity of different product structures, the mold production cycle is generally 12-30 days.

The mold finish and back to our factory will try it out. The mold trial time is 2-3 days. Mass production will be arranged after trial production samples are confirmed. The bulk delivery cycle depends on the product quantity and mold cycle.

Why can silicone keypads replace mechanical switch keypads in automotive applications?

Mechanical switch keys often suffer from jamming and a sudden heavy feel. Compared with mechanical switch keypads, silicone keypads have a simpler structure and a lower probability of failure.

More complex mechanical switch keypads require multiple sets of mold support, resulting in higher development costs and a longer development project cycle.

Automotive silicone keypads are more suitable for bad weather or outdoor use than mechanical switch keypads.
