Hard, rigid plastic delivering a crisp, mechanical feel dictated entirely by an underlying switch mechanism. Design & Integration Unibody construction allowing multiple keys, seals, and membranes in a single molded part. Simplifies assembly and reduces part count. Discrete keycaps requiring individual mounting on switches and supporting structures. More complex assembly with higher part count. Environmental Sealing (IP Rating) Inherent, excellent sealing against dust and moisture. Easily achieves IP67/IP68 ratings with proper design. No inherent sealing. Requires additional gaskets, o-rings, or membranes to achieve any IP rating, adding complexity and cost. Durability & Wear Resistance High cycle life (1-5 million+ actuations). Molded-in legends are virtually indestructible. Resists fatigue well. Durability depends on the switch (typically 20-100 million cycles). Legends can wear unless double-shot molded. Surface may gloss over time. Temperature & Chemical Resistance Exceptional range (-55°C to 200°C+). Excellent weather and UV resistance. Good chemical resistance to water, alcohols, diluted acids/bases. Limited range (approx. -20°C to 80°C/110°C). ABS yellows with UV exposure. POM has better chemical resistance but both are unsuitable for harsh environments. Cost & Manufacturing Higher tooling cost but lower per-unit assembled cost due to integrated design reducing labor and components. Moderate tooling cost but higher total assembled cost due to multiple components (keycaps, switches, PCB) and extensive assembly labor.

When silicone manufacturers receive orders, customers are generally required to provide either 3D drawings or physical samples of the products to be customized. 3D drawings are more convenient. They enable accurate price estimating, mold opening, and production. Why are 3D drawings so important? When we evaluate the price of silicone products, it is mainly divided into two parts:1. Mold price 2. Product price 3 factors affect the mold price. 1. Mold Material      (common steel types include NAK80, 718, S136...) 2. Mold Size            (common sizes are 250*250, 300*300 (unit: mm)) 3. The structure of the productThe more cavities a mold has, the higher the mold price.The product structure is complex, the mold-making process takes a long time, and the mold price is high. 3 factors that affect product unit price 1. Product size 2. Product structure 3. Product order quantityIn short, the price of a product is related to production efficiency. For example, if a simple structure product is produced 1,000 pieces a day, the unit price is $1. If a complex structure product is produced 500 pieces a day, the unit price is $1.5. So how do you know if a product is complex? Will a small structure greatly increase the difficulty of mold making? That depends on the 3D drawing of the product. The complexity of the product structure has a great impact on the cost and time of production. 3D drawings are tools that allow us to visually observe product structures and are essential for evaluating product prices.

●FDA Silicone Definition：FDA silicone refers to silicone materials that meet the safety and quality standards of the U.S. Food and Drug Administration (FDA). ●FDA Advantage:This type of silicone is usually used in scenarios where it comes in direct contact with food, beverages, medicines or medical equipment. It is widely used because of its non-toxic, odorless, high temperature resistance, and chemical corrosion resistance. ●FDA Silicone Application：FDA silicone must comply with relevant FDA regulations (such as 21 CFR 177.2600) to ensure that it does not release harmful substances during use and is suitable for food processing, medical devices, baby products and other fields.

Is there any charge for modifying the mold? Whether there is a charge for mold modification is a question that many custom customers have in mind.Why did the factory charge me for some minor changes? Are they trying to trick me into paying more? The first one is that after communicating the product requirements with the factory, if the product does not meet the standards, the customer does not need to pay for the mold and can just ask the supplier to improve the mold.The second is that after the product meets the requirements, the customer adds new changes to the product, such as adjusting the size of some areas. In this case, the cost of this change is the responsibility of the customer.To sum up, it depends on whether you have adequate communication with the factory about the product in the early stage.

Usually before Customing silicone keys, you need to confirm the product's hardness, color, process and other information. (For more information, please see my previous FAQ-What information is required to customize silicone products?) 1.Through STP Design, engineers design CNC programs to carve the required shapes on the steel. 2.After the prototype mold is made, the raw materials are refined. The required colors and special properties are added in this step. 3.Cut the raw materials into corresponding small pieces, put them into the mold and press them into the corresponding shape. This step is to transform the customer's design into an actual sample. The actual installation will show the test effect. The above is a sample production process. The following document is a detailed silicone rubber product customization process. If you happen to be customizing silicone rubber products, you can refer to the process.

1.Customize the information you need to provide From the perspective of a silicone supplier, let me show you the information you need to provide for custom projects As a silicone products supplier, we usually handle different information in three categories: 1.only ideaThose who only have ideas usually prefer to buy spot goods. It is only when they cannot find the right one in the market that they want to customize. Usually the customer's needs are not urgent. It is difficult to start the project.2. only samplesCustomers who customize based on actual samples usually purchase them from competitors and send them to Chinese suppliers to evaluate whether they can customize the same products. They have urgent needs for projects and want to quickly imitate their competitors' products to grab market share. It is also possible that the customer's equipment has damaged accessories and needs to be replaced according to the original size. Usually the demand is small and they are more sensitive to price.3.STP designCustomers who have STP format designs are very familiar with the silicone rubber industry, have a good understanding of product parameters, and have very clear goals. They also have their own engineers to work with. Their customization speed is the fastest because no additional adjustments are required. After confirming the requirements directly with the supplier, they only need to control the product quality. （Take the left button product as an example） The information you need to provide is as follows✔It is necessary to provide product design drawings, whether it is a sample or STP design✔Hardness of silicone rubber material✔Product surface technology，Printing/laser engraving/spraying, etc.✔The back process of the product, whether it uses conductive pills or conductive ink, or whether it does not need to be conductiveThe above are the questions that may be asked. In fact, customization may be a little biased.（If you want to know more about the process mentioned, click to jump to the corresponding page.）

Many customers will encounter problems with customized products. How to solve them? First, figure out if it's the supplier's mess-up or your order getting screwed.If it's the supplier's problem: 1. Snap some pics or videos to show what's wrong with the product. 2. Hit up the person in charge, tell him the issue, and sort out a fix. 3. Get him to comp you or remake it and ship it out.If it's the Client's problem:1.Place a new order and tell the supplier to produce and manufacture as soon as possible.2.For safe production, confirm all product information with suppliers before mass production. The most important thing is to check the information. And confirm whether the product is qualified at the sample stage. If you still don’t know how to do it, please tell the supplier to make it according to the sample. As a professional silicone product manufacturer, FromRubber is committed to solving detail problems for customers and reducing risks in the customization process.If you are customizing products, you may wish to contact us to listen to expert advice (free of charge for consultation) hah.

Tolerances for moulded rubber products As shown in the figure on the right, the tolerances of rubber products are in class M1/C. Usually silicone rubber products factory is to use this standard to determine whether the product meets the requirements. And this is also the international uniform standard.

Some silicone products have an unpleasant odor because manufacturers may use low-quality, inexpensive curing agents to cut costs. These curing agents, which are chemicals that help silicone materials harden, can release volatile organic compounds (VOCs) that cause the smell. Unlike our environmentally friendly curing agents that pass rigorous ROHS testing, these lower-quality options can leave behind residual odors. At fromrubber, we believe that customer satisfaction is our ultimate measure of success.

The Importance of Prototype Mold Manufacturing In the product development process, prototype mold manufacturing is a method used to quickly create initial molds for design validation, functionality testing, or small-batch trial production. These molds are usually simpler and more cost-effective than final production molds but still provide a good representation of the product’s design and functionality. Purpose of Prototype Mold Manufacturing Design Validation Prototype molds allow the design team to evaluate the product’s appearance, dimensions, and structure in the early stages, ensuring they meet expectations. Functionality Testing Small batches of products can be produced using prototype molds for performance testing, ensuring the product functions correctly under real-world conditions. Market Feedback Prototype molds can be used to create early product samples for presentation to customers or the market, gathering feedback to refine the design. Production Process Optimization Testing with prototype molds helps identify potential issues in the manufacturing process, allowing for improvements to streamline mass production later. Characteristics of Prototype Molds Lower Cost Prototype molds are generally less expensive to manufacture compared to final production molds, as they often use more affordable materials like aluminum, resin, or other easily processed materials instead of costly steel. Short Production Cycle The creation of prototype molds is relatively quick, making them ideal for rapid iteration and adjustments during the early stages of product development. Short Lifespan Prototype molds are less durable, making them suitable for small batch production or short-term testing, but they cannot withstand long-term, high-volume production. Before starting your project, please reach out to us to discuss how to create high-quality prototype molds. With our expert services, you can significantly enhance the success rate of your product development and ensure that your product better meets market demands.For more information,consult us now!
