Things you should pay attention to in the plastic electroplating. Posted on : June 27 , 2022 By GREFEE Can plastic be electroplated？ The answer is Yes! Compared to the metal parts, the electroplating plastic parts not only can achieve a great metal texture but also reduces the weight of products. With improving appearance of plastic and meeting the need of decoration, it also enhances the properties in the electric, thermal, and corrosion resistance. However, the material selection for electroplating…
Essential parts in metal electroplating
Post treatment methods of essential parts in metal electroplating Posted on : July 1, 2022 By GREFEE In the mechanical design, electroplating is a common surface treatment processing. Let’s take a look some common used metal electroplating processing. what is metal plating Electroplating utilizes the principles of electrocysis by coating a thin layer of other metal or alloy on the surface of a different metal to prevent the metal oxidation, such as corrosion to enhance its wear resistance, electric conductivity, reflection,…

Details you should know for the quality control
Details you should know for the Quality Control of Zinc die castings Posted on : July 7 , 2022 By GREFEE The zinc alloy die castings is increasingly becoming popular among zinc alloy die casting parts manufacturers. Since the requirements for the use performance are also increasing even though the physical quality of zinc alloy has been quite stable. To meet the requirements of customers, die-casting suppliers uses high-purity zinc alloy ingots with sticky process control system. In addition, the requirements for…
Differences between water cutting, laser cutting, plasma cutting and wire cutting
Differences between water cutting, laser cutting, plasma cutting and wire cutting in parts processing Posted on : July 19 , 2022 By GREFEE When we processing the parts, we often need to cut the plates first according to the drawings. There are some common methods include water cutting, laser cutting, plasma cutting and wire cutting. What is the difference between these methods? Laser cutting Laser cutting service is not limited to large part laser cutting, even could process small-scale parts. It…
Material selection for die cast metals
Material selection for die cast metals Aluminum alloy die casting, Magnesium alloy die casting, Zinc alloy die casting Posted on : June 24, 2022 By GREFEE Common metal die casting materials are various, such as aluminum alloy, magnesium alloy, zinc alloy, etc. Each material has different properties. According to the difficulty level of different cast parts, the cost spent on producing different materials vary greatly. Magnesium alloy castings ranks the highest among these three die cast metals due to its material cost and casting…
Slow or fast wire feeding, for wire cut parts?
Slow or fast wire feeding, for wire cut parts? Posted on : June 16 , 2022 By GREFEE What is slow wire-feeding? Slow wire-feeding is a type of CNC machine lathe that can fabric a high temperature of more than 6000 degrees to remove the ablated metals for cutting the workpiece through pulse spark discharge. There is a gap between the on-line electrode and the workpiece. So, the metal will be removed by continuous discharge. Edges of slow wire-feeding machining…
What are the common types of threaded holes
What are the common types of threaded holes? How to process threaded holes with CNC machining? Posted on : June 18 , 2022 By GREFEE Threaded holes fabrication: cutting and forming There are many types of screw thread in processing the threaded holes. The internal thread can be processed with the cutting tools (cutting tap or single lip cutting tool) or with a forming tap. Even though two methods bring the same effect. However, the following factors should be taken into…

How to manage die casting dies
How to Manage Die Casting Dies Posted on : June 21, 2022 By GREFEE Die casting mold is one of the three indispensable factors in aluminum alloy die casting mold production. Its use of it determines the service life of die casting mold directly. The production rate and the quality of aluminum alloy castings determine the cost, especially the custom die casting molds. So, die casting mold manufacturers have come to realize that only by putting more effort into the management, the molds…
Difference between shot blasting and sand blasting
Difference between shot blasting and sand blasting, which one? Posted on : June 9, 2022 By GREFEE Shot blasting uses the high-speed rotating impeller to throw the small steel shot or small iron shot to knock the part surface quickly to remove the oxide layer of the parts. Meanwhile, the lattice of the surface will distort when the steel shot or iron shot, which increases the stiffness. Shot blasting is often used for casting surface cleaning and part surface strengthening. Generally,…
How to select tools for CNC threads
How to select tools for CNC threads Posted on : June 14, 2022 By GREFEE Threads are the most common methods to connect the mechanical parts, whereas the threads holes processing is machining often at the end of the whole production. Once the processing is unqualified, the part might be scrapped or re-processed. Thus, it has a high requirement for the safety of processing. Processing thread holes requires various tools. Commonly used tools include the thread turning tool, tap, extrusion tap,…
