Revealing the Role of CNC and EDM in Mold Manufacturing: Creating the Perfect Silicone Keyboard

Welcome to our blog, today we will take you deep into the mold design and manufacturing process and answer your questions about the role of CNC and EDM in it. Mold manufacturing is a field full of technology and art, and CNC and EDM are indispensable magicians. Let us uncover this mysterious veil together and explore the mystery behind it.

First, let’s discuss the mold design process.

Mold design is the first and critical step in mold manufacturing. It requires combining the requirements of the product and the actual situation of the manufacturing process to create a digital model of the mold through computer-aided design (CAD) software. In the mold design of the silicone keyboard, the designer needs to consider factors such as the arrangement of the keys, the shape of the keys, and the stability of the overall structure.

The designer first draws a preliminary sketch of the mold based on the needs and requirements of the product. They then use CAD software to convert these sketches into digital models and perform detailed designs and adjustments on each part of the mold. This process requires designers to have rich experience and skills to ensure that the mold design meets the requirements of actual production and can meet various performance indicators of the product.

After the design is complete, the next step is the mold manufacturing process. CNC and EDM are two powerful tools in mold manufacturing that play a vital role. YJC Polymer uses world-class CNC and EDM. You can safely tell us your mold design and manufacturing ideas, and we will realize your ideas.

Have you ever wondered what role those seemingly mysterious abbreviations CNC and EDM play in the mold manufacturing process? Maybe you’ve heard of these technologies but are still confused about how they work and their applications. Don’t worry, let me unravel these mysteries for you today and take you to understand the magic of CNC and EDM in mold manufacturing.

First, let’s talk about CNC. CNC, that is, numerical control machine tool, is the abbreviation of “computer numerical control”. Simply put, it is a machine tool controlled by a computer program that can accurately cut and process a variety of materials, including metal, plastic, and today we are talking about silicone. In the mold manufacturing process, CNC plays a vital role.

The magic of CNC is its precision and versatility. Through pre-programmed instructions, CNC machine tools can automatically perform various processing operations such as drilling, milling, and turning according to design requirements. For silicone keyboard mold manufacturing, CNC machine tools can accurately cut and engrave the required shape and size of the mold according to the designer’s drawings and specifications. Whether it’s intricate grooves, protrusions or tiny details, CNC can handle them with ease.

What’s more, CNC’s programmability means it can quickly adapt to different design needs. In silicone keyboard manufacturing, a large number of mold changes are often required to meet different product models and customer requirements. With the help of CNC technology, we can easily adjust and modify the mold design and quickly realize the manufacturing of new molds. This flexibility not only improves production efficiency, but also makes customized production possible.

Next, let’s talk about EDM. EDM, or electrical discharge machining, is an advanced technology that uses the principle of electroerosion to process materials. In mold manufacturing, EDM is often used to manufacture mold parts with complex shapes, especially details and precision requirements that are difficult to achieve with traditional processing methods.


It’s amazing how EDM works. It generates high-intensity electric pulses on the surface of the workpiece, causing electrical corrosion of the metal materials on the surface of the workpiece, thereby achieving precise control of the shape of the workpiece. In silicone keyboard mold manufacturing, EDM can be used to process small complex parts such as micro-grooves, micro-holes or high-precision mold contours. These parts are often difficult to achieve with traditional machining methods, but with EDM, they are a piece of cake.

Not only that, but EDM can also process harder materials, such as carbide or mold steel. In the mold manufacturing of silicone keyboards, we often need to use these materials to ensure the durability and stability of the mold. With the help of EDM technology, we can easily process these higher hardness materials to ensure the quality and performance of the mold.

To sum up, CNC and EDM are two major artifacts in the mold manufacturing process. They respectively play the role of precision machining and complex shape processing. In the manufacturing of silicone keyboards, CNC is used to cut and engrave the basic shape of the mold, while EDM is used to process details and complex part molds. The two complement each other and jointly provide technical support and guarantee for the manufacturing of silicone keyboards.
