The injection parts stick to the mold, making it rather difficult for ejection.   Below are some reasons that caused the issue: 1. Too much injection materials. 2. Overhigh injection pressure, overlarge dwell pressure and overlong dwell time. 3. Overhigh melt temperature. 4. Overhigh mold temperature. 5. Incorrect design...read more

  Injection molds have a limited service life, appropriate measure can greatly extend this. Here share the methods which E-Mold used to cleaning, maintenance and storage of our customer's injection molds.   1. Cleaning and Maintenance of Heating and Cooling Channel Heating and cooling channels must be cleaned thoroughly to...read more

  The design of the component can have an enormous effect on the cost of manufacturing.   1.  Material Types The most easily machined types of metals include aluminum, brass, and softer metals. As materials get harder, denser and stronger, such as steel, stainless steel, and exotic alloys, they become much harder to machine...read more

  Basic Injection Mold Types   The most common injection mold types which used in E-Mold: two-plate mold; three-plate mold; hot-runner mold.   1. Two-Plate Mold A two-plate mold consists of two plates with the cavity and cores mounted in either plate. The plates are fastened to the press platens. The moving half of the...read more

Hard-coat with Teflon (MIL-A-63576A)     The main purposes of hard anodizing is to make the aluminum more resistant to corrosion. The PTFE(Polytetrafluoroethylene) coating is typically far thicker and harder than normal anodizing.   Types of PTEF coating: The anodic coating to be impregnated or coated shall meet the...read more

— Special Processing of Precision Mold & Rapid tooling in E-Mold Rapid Manufacturing   1. EDM   Electrical discharge machining process is: between the tool and workpiece continually occur pulsed spark discharges producing local, transient high temperature, which keeps the metal melting, gasifying and removing. Sparks...read more

There is a noticeable trend towards the use of aluminium alloys for medium- to high- volume production in recently years.   The principal advantages of this material are: 1. It costs less than steel. 2. It has good machineabilty: it machines up to 5–10 times faster than steel. 3. Distortion from machining is minimal compared to...read more

Stamping mold is the process to exert pressure on the blank so that the blank will undergo steel transformation or separation to produce workpieces with fixed sizes, shapes and properties, stamping process can be divided into separating and forming.   Common stamping process   1. Separating Process Process    ...read more
