Services In DitaiPlastic: Help You To Know Thick Gauge Vacuum Forming Well
Extrusion Plastic Sheets
Plastic sheets are the raw materials for the thick gauge vacuum forming process. Unlike the injection molding or rotational molding processes, which directly use particles to make products, before vacuum forming, we need to use the extrusion plastic machine to stir and melt the particles before extruding them into sheets. We can customize materials with different colors, sizes, textures, and properties according to different product needs. Properties such as flame retardant, UV resistance, corrosion resistance, high-impact, etc.; Textures such as smooth glossy surfaces, frosted textures, electronic textures, diamond textures, leather textures, hair-cell textures, fabric textures, etc. We have two sheet extruders, and all the raw materials come from Sinopec or Chimei. The advantage of this is that we can control the quality of the sheet from the beginning and can respond quickly to customize the required materials, or we can also make plastic laminated sheets to save overall costs. We believe that only high-quality materials can produce high-quality products.
Vacuum Forming Mold Production
When we receive your inquiry, firstly, we will need to know the application of the product, then we can suggest the material of mold which can be casting or block aluminum. Usually, casting aluminum can be cheaper, and it is used for solid-color products, which won’t see the dust and vacuum holes on the product’s surface. Block aluminum mold will do mirror polish, make the mold’s 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 dimensions and shapes different, just suitable for different materials. We also provide texture acid-etched mold if needed. Secondly, our mold engineers will convert the 3D drawing into mold drawing based on the material shrinkage, and use the right type of aluminum material for mold engraving, after engraving, we will drill 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, and can control the mold from quality, and cost to making time well at the first step. Molds are generally very durable, in fact, had tooling run for more than 10 years. And you are free to worry about the molds being broken, if anything bad happens to them, we will remake one for free.
Thick Gauge Vacuum Forming & Thermoforming
Vacuum forming or Thermoforming is a molding method for plastic products. It is cheaper and faster than the injection molding process. It usually only takes about 10 days to produce a sample, and the price of a vacuum forming mold is about 10% of that of an injection mold. The Vacuum forming process is not only suitable for products with large sizes and low minimum order quantities. It is also suitable for projects with many series, or fast iterations. Compared with injection molding, when the product requires mold modifications, there are also great advantages. We have 16 vacuum forming machines, including one fully automatic plastic vacuum forming machine with a maximum molding size of 4000*2000*1000mm. This is currently the largest vacuum forming machine in Guangdong and was designed by Mr. Zou Dehong, the general manager of DitaiPlastic. He has more than 30 years of experience in the plastic field. During the vacuum forming, we have a professional mold temperature gun, which has the most suitable mold temperature for different materials according to the different shrinkage. We will also adjust the sheet heating temperature to the most appropriate state based on experience. For some molding details, we will also add top-press mold or use the bulge technology base to assist with stretching. After vacuum forming, we will let the product cool for enough time to avoid product deformation and ensure a perfect plastic product.
CNC Cutting
CNC cutting is a necessary process for thermoforming products, it needs cutting the side material and drilling holes for the plastic process to get the designed shape. DitaiPlastic has 28 sets of CNC cutting machines, which have one of the largest numbers of CNCs in the vacuum forming field in China. In the beginning, our engineers will convert 3D drawings into drawings suitable for CNC cutting, and then they will make the corresponding mold according to the shape of the product. How do we maintain accurate cutting: First of all, our CNC machines are 5-axis robot hands, which can process 360 degrees in all directions and are fast. And will make a wooden or fiberglass jig/fixture with small air holes according to the shape of the products. Then insert the magnets into the jig, the other side of the magnet will be placed on the product surface to make it match the jig tightly, the small vacuum holes on the wooden jigs will pump out the air between the product and mold so there is a vacuum state between product and jig. These two steps to make our products fit perfectly with the jig then we get a perfect cut product.
Vacuum Forming Prototyping
Vacuum forming prototyping is an advanced integrated technology that combines vacuum forming with injection molding, rotational molding, 3D printing, machining, and hardware processes. In the current market, especially in fields like new energy, artificial intelligence, and medical aesthetics product updates and iterations are rapid, it plays a pivotal role. This method effectively realizes complex product shapes at a reduced production cost, ensuring the finished products have excellent stability and precision. In early 2010, DitaiPlastic established the vacuum forming prototyping department. The engineering team breaks down the components, specifying which particular type of process is used for each component. By integrating vacuum forming techniques with various parts and employing multiple unique bonding methods, followed by two polishing processes, and finalized with professional painting, the complete set of products appears as a single component. This results in a product that is aesthetically pleasing, durable, stable, and of high quality, exceeding customer expectations.
Quality Control
DitaiPlastic is committed to continuous optimization and refinement of its departmental structure. Currently, the company boasts various departments such as Engineering, Molding Making, Sheet Production, Vacuum Forming, CNC Cutting, Post-Processing, Prototyping, Painting, Warehouse Management, and Quality Control. The Quality Control department plays a crucial role throughout the product manufacturing process. For every key production stage, the Quality Control department is equipped with corresponding inspection methods. For instance, products from the Sheet Production department undergo tests for performance, thickness, and color, using specialized equipment, calipers, and colorimeters. For vacuum forming products, thickness and surface quality are assessed using ultrasonic thickness gauges and gloss meters. Beyond overseeing inspections for each production step, the Quality Control department also compiles and provides detailed inspection reports based on specific customer requirements. To ensure product quality, the inspection process typically includes initial checks, random sampling, and routine inspections. This ensures that every product leaving the DitaiPlastic factory meets the customer’s expectations and standards. Furthermore, DitaiPlastic places emphasis on staff training and skill enhancement to adapt to the rapidly changing market and the ever-growing demands of customer.
Post-Processing/After-Treatment
We can complete all post-processing of plastic products in-house, such as deburring after CNC, grinding, gluing, polishing, painting, silk-screen painting, electroplating, packaging, etc. DitaiPlastic has a dedicated post-processing department and three spray painting production lines, which can meet Customer’s requirements for products. For instance, we provide a variety of paints, the most commonly used of which is PU paint. This paint is mostly used in automotive products. It is not easy to fade and has certain anti-UV properties. In addition, there are other paint types: skin-like paint, matte paint, anti-reflective paint, impact-resistance paint, etc. There are also a variety of packaging options available, including cartoon packaging, wooden box packaging, pearl cotton packaging, etc. After all these processes, the plastic will no longer be a simple or single-piece product, it can be a complete car cover, a robot, or even a real airplane, so if you have a complex project, please feel free to contact us get in touch and we’ll make sure you find a plastics expert.
