Oalyer FFP2 and FFP3 Face Masks Company in China

Dongguan Olayer Technology features FFP3 face masks to support health care professionals and other individuals. 

Dongguan Olayer Technology,  is KN95 mask China Company, is presenting its advanced range of FFP3 face masks for workers, doctors, and other people. In the past, personal protective equipment was limited to the health care and medical sector. After COVID-19, PPE is a necessity for everyone all around the world.

Nowadays, COVID-19 has turned into a pandemic. It is spreading quickly all over the world. For protection from the coronavirus, preventive measures are becoming crucial for everyone. Wearing an FFP3 mask is becoming a necessity for everyone, either healthy or sick.

In the initial days, the demand for PPE equipment was greater than its supply. Several companies like Olayer started mass production of USD ky FFP2 face mask and FFP3 masks. These masks are available easily in the market. Undoubtedly, it is essential to wear masks to stop the spread of this disease. Several studies prove that individuals can spread this virus even without visible symptoms of Corona.

People can stop the transmission of this disease by wearing the best face mask. Basically, KN95, N95, FFP2, and FFP3 are suitable options. These are better than standard masks to filter over 95% of particles and dust. In Europe, FFP2 and FFP3 face masks are hot-selling protective masks. FFP2 face masks of Olayer offers protection against solid and liquid aerosols. It is suitable for plastering and sanding.

The Benefits of Metal Stamping Tool

Consider where you will employ your metal stamping dies kit as a way to figure out the ideal size. Metal stamping is a process that’s imperative for a selection of sectors, and our group of engineers and manufacturers will work together with your company to ensure that your needs are satisfied. Though most metal stamping tool kits are alike, there are plenty of differences worth noting. A round part requires around stripper ring thus a cylindrical grinder may be used. A stripper plate is just a plate that is used to push part of an injection mold core. After the epoxy curing, the rest of the portion is full of a high alumina cement strength to lessen mold manufacturing price.

How to identify the quality level of the recycled plastics materials

1. The glossiness of surface is an important indicator to measure the quality level of particles of all kinds of recycled materials. Recycled materials of good quality have glabrous and smooth surface.

2. Transparency is also an important indicator to measure the quality level of particles of middle and high-grade recycled materials. Materials with the good transparency are usually of good quality.

3. The uniformity and consistency of color is an important indicator to measure the quality level of particles of colored recycled materials. For example: white, creamy white, yellow, blue, black and other colors

4. The density of particles is an important aspect to inspect the level of the regeneration process. 
Poor plasticizing and loose particles

5. To test whether the recycled particles sinking water or not can be used for inspecting the stuffing content of PP and PE.

As for recycled materials, different recycled materials have different applications, as there’re no uniform standards and it is also difficult to institute it. The only standard if have to say is to well meet production requirements of the users.

Procedures for control of injection pressure

The control of the injection pressure is usually divided into an injection pressure, the second injection pressure (holding pressure) or more than three times the injection pressure control. Switching time pressure if it is appropriate to prevent mold pressure is too high, to prevent overflow or lack of material are all very important. Mold making packing stage the specific volume depends on the gate closed when the melt pressure and temperature. If the holding pressure time to switch to products from the cooling phase of the same pressure and temperature, then the specific volume of products will not change. Plastic Molding at a constant temperature to determine product size is the most important parameters of the packing pressure, affecting the product dimensional tolerances of the most important variable is the holding pressure and temperature. For example: after the end of the filling, packing pressure decreased immediately, when the surface to form a certain thickness, packing pressure to rise again, thus forming a low clamping force of large thick-walled products, elimination of collapse pits and flash.

Holding pressure and the speed is usually highest when the plastic cavity filling pressure and speed of 50% to 65%, which is holding pressure lower than the injection pressure of about 0.6 ~ 0.8MPa. As the packing pressure lower than the injection pressure, holding pressure in the considerable time, the pump load is low, solid pump life is extended, while oil pump motor power consumption is also reduced.
Three pressure injection filling both the smooth parts, and weld line does not appear, depression, flash and warpage. For thin-walled parts, small pieces of long, long process of molding large parts or even the cavity mold configuration is not balanced and not too close parts of the molding as a whole. the amount injected into the mold cavity filling process control of plastic
Regulate the use of certain measures in advance so near the end of the injection stroke, the screw end is still a small amount of residual melt (buffer capacity), according to the mold filling was further applied injection pressure (injection pressure two or three times) , add little melt. This can prevent depression or adjustment products product shrinkage. screw back pressure and speed of the process control
High back pressure can be intense shear melt at low speeds, will also get a long plastic tube in the machine plasticizing time. Therefore the current use of more back pressure and speed of parallel programming control. For example: measurement of the whole trip in the screw first high speed, low back pressure, and then switch to a lower speed, high back pressure, and then switch to high back pressure, low speed, and finally in the low back-pressure, low speed for plastics , so that the front screw melt most of the pressure be released, reducing the rotational inertia of the screw, thereby improving the accuracy of measurement of the screw. Often result in excessive back pressure increases the degree of stain color; pre-plastic bodies in increased mechanical wear screw and barrel; pre-plastic periodic extension of decline in production efficiency; nozzle prone to drooling, regeneration feeding amount increased; even with self-locking nozzle, if the back pressure higher than the design of the spring closure pressure may also cause fatigue failure. So, back pressure must be properly adjusted.

3D CAD design for plastic injection molding

Over the years, 3D CAD systems such as SolidWorks have become more and more integrated into the design and manufacturing processes. Plastic injection molding is no exception. Industrial designers use 3D CAD to make ergonomic and aesthetic contours which would be next to impossible to communicate in 2D drawings. Modern toolmakers must use 3D models to make the mold cavities. Also, most rapid prototyping machines accept only 3D files to create parts.

Rebling Plastics has extensive experience using SolidWorks and CADKEY to design parts for plastic injection molding. While formats are constantly changing, we have successfully imported from and exported to virtually all other CAD programs, including Pro/ENGINEER, CATIA, Solid Edge, Inventor, and AutoDesk/AutoCAD. In addition, we use universal formats such as IGES, STEP, DXF, DWG, parasolid (x_t), STL, and many others.
