injection moulding services
Degree of dependence of industrial products on injection molding services
Almost all industrial products must be moulded.The high precision, high consistency and high productivity of the moulds are incomparable with any other processing methods.So industrial products on the mold dependence degree is very high!
Injection molding services is a kind of industrial product that makes materials form in a certain way in a specific structural form. It is also a kind of production tool that can batch produce parts of industrial products with certain shape and size requirements.From airplanes and automobiles to teacups and nails, molds, to a great extent, determine the quality, efficiency and ability of new product development.So the mold has the honorary title of "mother of industry"

plastic injection molding parts,The difference between Sinker EDM and Wire EDM is mainly due to the type of electrode used in each process, Sinker EDM does not require pre-drilling, and the 3D capability that Sinker EDM can achieve, that is, Wire EDM only has the capability to produce 2D parts.
Wire-cut discharge machining (EDM) is a method of cutting metals and other conductive materials in which a moving wire dissolves the material in a controlled manner.In wire-cut edM, a wire (usually made of brass or layered copper) between 0.1 and 0.3 mm in diameter is used as an electrode and actually arcs with the part to be cut to form the desired shape or form.(If there's anything else you require assistance with, be sure to send another message!)
plastic injection molding partsBecause some complex parts can only be realized with THE help of EDM, it is widely used in aluminum parts processing as an auxiliary process.It is difficult to remove corners for parts with deep structure. If only CNC machining is used, a large radius will be left in corners, which is not allowed in some cases.By using the EDM process, sharp edges can be maintained.EDM applications include blind cavities (keyways), complex details, sharp corners, fine surface treatments, thin walls, and more.

rapid tooling!What are the advantages of EDM
Electrical discharge machining (EDM) is a new technology completely different from mechanical machining,plastic injection molding parts
Electro discharge machining (EDM) can meet the needs of production development, and has shown many excellent performances in application.
The characteristics of EDM are as follows:rapid tooling (If there's anything else you require assistance with, be sure to send another message!)
1. During machining, there is no contact between tool electrode and workpiece material, and the macroscopic force between the two is very small.The tool electrode material does not need to be harder than the workpiece material, so the tool electrode is easy to manufacture.The high energy density of pulsed discharge facilitates the processing of special materials and workpiece of complex shapes which are difficult or impossible to be processed by ordinary machining methods.It is not affected by the hardness of the material and the thermal treatment condition.
2. The high energy density of pulse discharge facilitates the processing of special materials and workpiece of complex shapes that are difficult or impossible to be processed by ordinary machining methods.It is not affected by the hardness of the material and the thermal treatment condition.The duration of pulse discharge is very short, the heat conduction and diffusion range generated during discharge is small, and the range of material affected by heat is small.
3 can reform the workpiece structure, simplify the processing technology, improve the service life of the workpiece, reduce the labor intensity.

plastic injection molding parts Based on the above characteristics, the main USES of EDM are as follows:
1) Manufacturing die, plastic die, forging die and die casting die.Machining holes, deformed holes and threaded holes in cemented carbide.
2) Cut out the parts on the sheet metal.Process narrow seams.
3) Grinding flat and round surfaces.Others (such as strengthening metal surfaces, removing broken tools, perforating quenched parts, direct machining of complex parts).
Features of EDM mirror finishing center
The surface of ordinary EDM is rough;There is often a pear-skinned white layer on the surface of the workpiece, which is extremely brittle and has many microcracks, and there is tensile stress, and its fatigue resistance is relatively poor, thus greatly affecting the service life of the parts [1 ~ 4].The results show that when the surface roughness is less than Ra0.3 m, the fatigue resistance of the electromachined surface is similar to that of the machined surface, and there is no microcrack

The specular EDM method can effectively solve the problem of parasitic capacitance between electrodes.However, there are also some problems in the powder mixing method. For example, to solve the problem of uniform mixing of fine powder in the working liquid, the fine powder will cause environmental pollution, and the cost is relatively high, so it has certain limitations in practical application.The author found in the research of electrospark mirror processing technology that mixing gas in the working fluid of the machining clearance can effectively reduce the surface roughness of the workpiece and greatly improve the productivity.
Edm technology is widely used in mold manufacturing and the processing of difficult materials

A.So it is an important direction for the development of electro discharge specular machining (EDM).The research on electrospark mirror processing technology in foreign countries was carried out earlier and achieved good results.Sodick company pioneered the study of edM technology in the late 1970s.The research of early EDM technology is mainly confined to reducing and controlling pulse discharge energy
B. For example, Sodick company launched the first generation PIKA power supply with narrow pulse width and low peak current in 1980, and its surface roughness was less than Ra0.1 m.In this period, the mirror processing was mainly limited to the small area of super finishing
C For a large area of EDM, due to the pulse accumulation effect of parasitic capacitance between electrodes, the actual single-discharge energy of the gap is greater than the single-pulse energy provided by the pulse power supply, thus affecting the reduction of the roughness value of the machining surface. The larger the area, the greater the influence

D and the powder mixing process.Therefore, scholars at home and abroad have put forward many technological methods.For example: split electrode method simple electrode generation method, conjugate rotary processing method
E Local electric field induction method in edM grinding, etc. Among them, powder mixing processing method was developed by Japanese scholar Maori Shangwu, etc
What factors will affect the speed of linear cutting
Generally according to the surface roughness requirements to choose.Therefore, the most critical factor affecting the processing speed is the thickness of the workpiece.
The main working principle of wire cutting is: a capacitor is formed between the workpiece and the electrode wire. When the distance is very close, the surface is convex (because the workpiece has surface roughness, from the microscopic point of view, the surface of the workpiece is uneven). Partly because the distance is closer, local breakdown of capacitance is likely to occur, resulting in local short circuit.The heat generated by the short-circuit current makes the local temperature rise sharply and vaporizes and corroded the convex part of the surface to remove the material.

1. The main factors affecting the processing speed are the thickness of the workpiece and the current:
2. The thicker the workpiece, the larger the area to be vaporized, and the processing speed naturally decreases;
In addition, the short circuit current cannot be infinite, otherwise the machine will be destroyed directly. A cut-off value must be set. When the short circuit current reaches this setting value, it will not rise any more.Therefore, if the current cutoff value is set to be large, it means that the current is large, the heat generated is large, and the corrosion rate is naturally accelerated.(If there's anything else you require assistance with, be sure to send another message!)

However, the current is too large and the corrosion is large, which is unfavorable to improve the surface quality of the workpiece.current

Three dimensional measuring instrument, mainly refers to a three-dimensional point to carry on the measurement of a kind of instrument, the market also has called three coordinates, three coordinates measuring machine, three dimensional coordinate measuring instrument, three dimensional coordinate measuring instrument.
Three coordinates and three dimensions are the same thing, but some people call it different, it's a tool for space measurement.The main principles are:
By placing the measured object in the three-dimensional measurement space, the coordinate positions of the measured points on the measured object can be obtained. According to the spatial coordinate values of these points, the geometric dimensions, shapes and positions of the measured object can be calculated.Basic principle is through the detection sensor (probe) and measurement of spatial axis movement, the geometrical element to be measured in discrete space point location, and then through the certain mathematical calculation, the completion of the analysis of the measured point (point group) by fitting, eventually restore the measured geometric elements, and on the basis of the calculation with the theoretical value (nominal value), the deviation between the measured parts to complete the inspection work.
