CNC MACHINING SERVICES CHINA TO MAKE A MIRROR SURFACE BY USING SINKER EDM

What Is CNC Machining?
CNC machining is a subtractive manufacturing process where raw material is removed with a variety of precision cutting tools to make a part or product. Advanced software is used to control the equipment according to the specification of your 3D design. Our team of engineers and machinists program the equipment to optimize cutting time, surface finish and final tolerance to meet your specifications. We use CNC machining not only to manufacture parts and prototypes but also to make mold tools, which can be used for our plastic injection molding or pressure die casting services.
The Sinker EDM machining process uses electrodes that are electronically charged and configured to specific geometry to burn electrode geometry to metal components. The Sinker Electrical Discharge Machining process is a process that is commonly used in the production of molds and dies. It works by having two metal parts submerged in an insulating liquid connected to the current source which is then switched on and off automatically in relation to the parameters that are set by the controller. Electric tension is what is created between the parts when the current is on.
When brought together, the two parts of the metal heats up to a melting point; when the electrical tension is discharged and spark jumps across. Innumerable spark sprays gradually shape the desired form into the metal depending on the electrode shape. The Sinker EDM process is most suitable for those looking to minimize machining risks with accuracy and reliability. One of the major benefits of the process is the ability to produce shapes that are more complex without inducing stress onto the material. It doesn’t cut all the way through the material unless this is a requirement and thus it is a process that has a wider variety of applications including thin walls, blind cavities and cross sections. The efficient technology is great for injection molds and stamping dies and can be used to make the mirror surface too.
How mirror surfaces are done
Mirrors are smooth surfaces that have a shiny dark background that reflect well. Polished metal reflects extremely well and this is something that can be achieved by the sinker EDM. The common raw materials that are used in mirror making include glass, but because it is a poor reflector, it needs a metal layer on its surface to create an even surface with impressive reflection. Plastic substrate works as well as glass and it is commonly used in making mirror surfaces for children’s toys. Injection molding is what is applied to create the desired shape, whether circular or flat, transparent or opaque. Generally, the base materials need to be coated to make a mirror and this is where the sinker EDM comes in handy.
· First, the outline of the blank material is made to suit the application. The final shape desired is what determines the cutting method. The cutting is done before the metal coating takes place.
· Blanks are then placed in optical grinding machines and gritty liquid that is the grinding compound is spread over the blanks as they rub against curved surfaces.
· After the polishing of the surface into a smooth finish, a coating with the desired reflective material is then done. The Sinker EDM is used to heat the metals so they can vaporize and get deposited on the surface. Precision is needed to ensure that the timing and temperature are just right in getting the right thickness and uniformity is achieved in the end.
· Masks and metal stencils can be applied to the surface to create patterns and dielectric coatings can also similarly be applied as reflective layers or protective layers over the metal ones. A number of evaporation steps maybe necessary for multiple layer coating before the mirror is mounted on the base and packed in shock resistant packages.

JASONMOLDING TELL YOU HOW TO PRODUCE HIGH QUALITY INJECTION MOLDED PLASTIC PARTS

JasonMolding, China’s leading plastic injection molding company is pleased to present their custom plastic injection molding along with a variety of molding and dies development and manufacturing services. For over 10 years now, the company has been involved in plastic injection molding and this process involves producing plastic parts in high volumes using the most recent techniques and machinery. Heated barrels and special mold cavities are used to create precise shapes, forms and sizes of various plastic objects.
Injection molding is an accessible, ubiquitous process that you can use in the manufacture of different products. This process is quite versatile, making it a very good choice for products, but you must be careful with the process and the product design if at all you are to get efficiently molded plastic parts that are high in quality. The decision you make in the production process will largely determine the final products that you are able to achieve. Fortunately, using a few design principles, you can get the high quality plastic parts that you need from injection molding.
Remember the process necessities.
Injection molding has two halves of mold hollowed using the negative image of the part before the hot liquefied plastic is injected into the mold and left to cool. The two halves are then pulled apart when cooling has taken place effectively. Remember to position the gate properly so that removal of finished product does not interfere with the part integrity. Because the plastic material will shrink in the cooling process, be careful with the part dimensions and design elements to get high quality results. You also want to think about the parting line when making the design so it is located in an appropriate area on the final product during part release.
Pay attention to wall thickness
One of the best things you can do when manufacturing plastic parts is to design with manufacturability in mind. Whereas most manufacturers may work with a uniform wall thickness for injection molds, shrinkage factor during cooling process can lead to improperly designed molds and also products. Let thicker areas be on lower mold parts so that gravity can help in still-cooling the materials in all the right ways.
Do proper cooling and ejection
Quality injection mold does not only rely on how the process is handled but also on how effective and efficient the cooling system is. The mold should maintain consistent temperature to avoid warping and shrinkage while at the same time minimizing cycle times for maximum production output. Ensure therefore, that the cooling system for your plastic parts is well-designed for quality purposes. Releasing parts from mold should also be done with care. Ensure that cycle times, type of ejection mechanism and placement of ejector pins are calculated with precision so that defects are kept minimal on the final product.
Run samples to improve quality
One of the best ways of avoiding rework on your mold cavity it to create a sample mold first to test run your part. This move will help in determining whether there should be any adjustments to the mold or molding parameters and resin selection. Any quality issues can easily be collected through sampling the part and this saves money and time. When you run samples you are able to ensure that the final parts are up to expected standards.
Your injection mold maker should be good enough to avoid the common mistakes experienced, especially when dealing with plastic parts.
China plastic injection molding results are as good as the injection mold maker you choose. Think your part through before choosing the best China mold manufacturer.

BENEFITS OF PLASTIC INJECTION MOLDING TECHNOLOGY FOR PLASTIC INJECTION MANUFACTURING PROCESS

The plastic injection molding method is one of the most used techniques for producing a high volume of plastic parts. This method relies on a heated barrel and a special mold cavity to create the precise shape and size of different plastic objects. Here are a few of the benefits of using plastic injection molding technology:
Intricate and complex shapes
The plastic injection mold technique makes it possible to create the highly intricate and complex shapes. The plastic placed in the mold is put under an extreme level of pressure, which makes it a lot easier to create the parts with great details. This molding process is more effective than other options because of the high pressure and makes it a lot more cost-effective to produce the complicated shapes.
High efficiency
The actual process of molding is fast and efficient. Once the mold has been built to the customer’s specific needs, the creation of the component doesn’t take that much time. Plus, the efficient nature of this molding technique means it is able to create the parts in a single piece. The fast production output means the entire process is a lot more cost-effective than alternative options in the market.
Improved strength
This type of molding makes it possible to use fillers in the injected material to help increase the strength and durability. This is useful in fields that require the most durable parts that cannot be created by the alternative molding processes.
Use different plastics simultaneously
A significant benefit of using the injection mold technique is the ability to use several types of plastic at the same time. By co-injection the mold material it is possible to use the preferred type of plastic that is completely customized and gives the preferred strength and texture.
Cut manufacturing costs
The automated process of injection mold means it is very cost-effective and mainly operates using robotics and machines. The work is easily supervised by one controller, which helps to cut back on overheads and manufacturing costs. Also, the automated nature of the production means the parts are produced to a very accurate standard on the first attempt which will cut back on a lot of waste material. The high accuracy level is achieved with the help of the latest computer aided manufacturing (CAM) and computer aided design (CAD) technologies. Once the part is released from the injection mold it has a high-quality finish and looks much like the finished article with no further work required.
