Also, we have always maintained the enthusiasm to study new technologies and new methods, in order to make our vacuum forming manufacturing cost lower and more efficient, In the last few years, we passed the audit of LV, Guerlain, Wistron, KTC, Hisense, and so on, we also got an honor plaque from the anniversary of China 70th through the cartridge boxes we made. 

Our Process: Help You To Know Thermoforming Well

Extrusion Plastic Sheets

Plastics sheets are the raw material of thermoforming process, unlike injection or rotation process which use the grain to directly make products, so before thermoforming, we will need the machine to extrusion grain to sheet, we can customize the material with different properties according to clients’ requirements, such as flame retardant, UV resistant, corrosion-resistant, high impact, texture, smooth shiny surface, etc. we have two extrusion machines, we can control the quality at the begining, we can exactly know what our raw material is, and it is recycled or virgin, and which brand it is from, which is quite important for the quality of final products, The high-quality materials can fabricate the high-quality products.

Thermoforming Mold Production And Suggestions

When we receive your inquiry, firstly, we will need to know the application of the product, then can suggest the material of mold which can be casting or block aluminum, Casting aluminum can be cheaper, and it is used for solid color products, which it won’t see the dust and vacuum holes on the product’s surface, Block aluminum mold will do mirror polish, make the mold surface shiny and smooth, then it hard to attach the dust, so usually transparent products will need block aluminum molds, these two kinds of molds won’t make dimension and shape difference, just suitable for different materials; Secondly, our mold engineers will convert the 3D drawing into mold drawing based on the material shrink, and use the right type of aluminum material for mold engraving, after engraving, we will make air holes and polish the mold surface to avoid negative impacts on the product surface. To make a perfect plastic product, one of the necessary conditions is having a perfect mold. We have our own CNC mold machines. We can control the mold from quality, and cost to making time well. Tools of far greater durability. In fact, had tooling run for more than 10 years. So don’t worry about the tools Being broken, if something bad happens to them, we will remake one for free.

Thermoforming & Vacuum Forming

Thermoforming or vacuum forming is a molding method of plastic products, which is cheaper and faster process than injection process, usually it needs around 10 days to work out the samples, and thermoforming mold price is around 10% of injection mold, thermoforming process not only suitable for large size and less moq projects, but also big quantity projects, we have 16 sets of vacuum forming machines, in which there is one full-auto plastic vacuum forming machine, the maximum forming dimension can reach 4000*2000mm, which is currently the largest plastic machine in Guangdong, and it designed by the general manager of Ditai Mr.Zou Dehong, which have more than 30 years experience in vacuum forming field, we will adjust temperature to the most suitable state, we can also add the top plug to assist stretching. And after vacuum formed, we will let the products cool enough time, so they can avoid it out of shape, then make sure get a perfect plastic products.

CNC Cutting

CNC cutting is a necessary process for thermoforming products, it needs cutting the side material and drill holes for the plastic process to get the designed shape, Ditai has 28 CNC cutting machines, which has one of the largest numbers of CNCs in the thermoforming field in China. In the first beginning, our engineer will convert 3D drawings into drawings suitable for CNC cutting, and then he will make the corresponding mold according to the shape of the product. How do you want the product shape most accurately cut off? First of all, our CNC machines are 5-axis robot hands, which can process 360 degrees in all direction and is fast. And will make a wooden jig with small air holes according to the shape of the products. Then insert the magnets into the jig, on the other side of the magnet is placed on the product surface to make it match with the jig tightly, the small vacuum holes on the wooden jigs will pump out the air between the product and mold so that there is a vacuum state between them. These two steps make our products fit perfectly with the jig then get a perfect product.

The Treatment Of Products

We can do all the treatments of plastic products in-house, such as Assembly, Gluing, Polish, Painting, Silkscreen, Electroplating, etc, we can meet the high requirements of customers, and the products can be widely used in various industries, we have a professional team to guarantee the quality, and we have the certification for this kind of process, which is hard to get it in China, also the painting can achieve UV protection,scratch-resistant, shade the light, which usually used for outside and machine parts. After all these processes, the plastic won’t be an easy or single piece anymore, it can be a full car cover, robot, or even a real plane, so don’t hesitate to talk with us if you have complicated project, we will make sure you will take to a plastic expert.

Due to the impact of  COVID-19, many clients can not visit us in person. This video is for you to know more details about our factory. Hope you will like it.
