Introduction: CNC milling is a highly efficient subtractive manufacturing process used to create precise parts from metal or plastic materials. This article aims to provide insights into how CNC milling works, the role of G-code programming, the use of advanced CNC machines, and the finishing options available for the produced parts. Fixturing and Material Preparation: The CNC milling process commences by securely fixturing a block of metal or plastic material inside the CNC mill. [...]

3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file. The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive layers of material until the object is created. Each of these layers can be seen as a thinly sliced cross-section of the object. 3D printing is the opposite of subtraction manufacturing which is [...]

Understanding Tool Change and Tool Position Points in Five-Axis CNC Machining Centers Introduction: Five-axis CNC machining centers are advanced machines used for precise and complex machining tasks. This article aims to explain the concepts of the tool change point and tool position point in these machining centers and how they impact the machining process. Tool Change Point in Five-Axis CNC Machining Centers: The tool change point in a five-axis CNC machining center refers to [...]

CNC metal manufacturing plays a vital role in providing high-quality production services and technical support for various industries, including transportation, technology, and more. Metal surface treatment is essential to achieve specific properties of parts and prolong their service life. Below are commonly used surface treatment processes for metal products, which can be evaluated and selected based on the specific use environment.   Anodizing: Anodizing is primarily applied to aluminum and aluminum alloy materials. Using [...]

This is Bryan, today I’m telling you what information you should know from DFM report, why it’s so importance? When we making a new mold, a Design for Manufacturability (DFM) report is a critical tool that provides valuable information to ensure the design is suitable for efficient and cost-effective manufacturing processes. Below are some key points of information you should know from a DFM report: 1.Part Geometry: The DFM report should include detailed information about the part's geometry, [...]

This is Bryan from Shenzhen RJC company, today we’re talking about the connection and application of insert mold and connector. Firstly, let's talk about what is a insert mold? It is generally the combination of metal parts and plastic into a new product. There have some ways to go, put the metal parts into the plastic mold then inject plastic material and make them stick together, this kind of products are high precision requirements. In addition, there is hot melt, which is to heat metal parts [...]

This is Bryan from Shenzhen RJC company, today we’re talking about how to choose the suitable gate for injection molding parts. Firstly, we need to know how many gate types of general used in plastic injection molds. Sprue gate, Side gate, Fan gate, Pin gate, Sub gate, and Banana gate, these normally use to cold runner system, or using with hot runner system together. About the hot runner system, from the gate types, there have Sprue gate, [...]

This is Bryan from Shenzhen RJC company, today we’re talking about how to choose cold runner or hot runner system for medical products. When we’re designing a medical mold, choosing between a cold runner and a hot runner system depends on several factors such as the type of material, part design, production volume, and cost. Use hot runner systems in medical molding can offer significant benefits in terms of productivity, quality, and cost-effectiveness. However, it is important to [...]
