hello sir, it is 720mm, however, our largest processing size is 4000*2000*1000mm

Thanks for your reply. I will make contact with WhatsApp

Generally speaking, to calculate the size of a sheet, one must measure the length, width, and height of the product. For some special structures, more material is required to meet the molding requirements. The specific dimensions of the sheet should be calculated based on the actual product size and structure. As for the thickness, the thickness of the sheet reduces as it stretches over the mold during forming. This depends on several factors: 1. Material characteristics, as different materials have different stretching properties, even under the same conditions; 2. The thicker parts of the product typically show more noticeable thinning and will have some differences in thickness compared to the edges; 3. The degree of thickness of the sheet directly determines the thickness of the product after molding, so we usually use a slightly thicker sheet to meet the thickness requirements of the molding. Overall, the actual calculation of sheet thickness and the estimation of product thickness should be determined based on the actual size and structure of the product.

If l*b*h is 800x650x350 mm what sheet size you suggest for HDPE/PP material.What drop will be for 350 mm height in HDPE/PP as finished product should be 4 mm thickness

@@hrishikeshpiyush9652 we suggest use 1200x1050mm material.and the thickness of raw material will need check the shape to suggest

Hello~

could you please let me know what can I do for you?

we call it plastic sheets extrusion machine

Thank you for your inquiry regarding the raw material grade. At DitaiPlastic, we exclusively use high-grade materials compliant with international standards (ISO, ASTM) to ensure superior quality and performance for all our vacuum formed products. For specific material grades and their applications, please feel free to reach out to us directly.

yes, We embed magnets to keep the product firmly attached to the jig

@@vacuumforming great idea. We use vacuum cup 👍

thank you for your recognition：）@@r.3170

Could you please let me know what price do you need?

thank you for your comment, unfortunately we don't sell machines, we only do custom vacuum forming parts, wish you a great day :)

Thank you so much!!

This is PE :)

Thank you so much!!! much appreciated:)

Sorry for the late reply. We have PC thermoforming. This is our manager’s WhatsApp number: 13825780422. Thank you very much for your message ：）

Thank you for your careful observation. I don’t see any flaws here. Can you elaborate?

Our factory is in Liaobu, Dongguan, Guangdong, China :)

Thank you for your asking, small products are made in the same way :)

Ok thanks. But there must be limitations

When the product is very small, multiple molds will be made and vacuum-formed together. As long as the shape meets the requirements, it can be done@@CompanyBusinessCards

Vacuum forming is beneficial over injection molding mainly due to lower tooling costs, faster prototyping, and design flexibility, making it ideal for large, lightweight, and short-run items. It's less expensive for small-scale production and can handle a wider variety of shapes and sizes. On the other hand, injection molding is favored for high-volume production due to its strength, durability, and ability to produce complex parts with precision.

@@vacuumforming thank you

No. 6 Daxing Street, Quantang, Liaobu Town, Dongguan City, Guangdong Province, China, you are welcome to visit :)

If you have any questions, we'll be happy to answer them ：）

This is PMMA

Thank you so much!! We are very sorry that we did not receive your email, may I get your email address?

Thank you! First of all, there will be equipment on the machine that can clamp the sheet. When the mold is heated, there will be a certain distance from the sheet. Also, our operators are experienced and have a relatively suitable heating temperature for different materials or thicknesses. Finally, we will make samples before production to ensure that the production is correct.

Thank you! After vacuum forming is completed, there will be a cooling device above the product to blow cold air to assist in faster forming. :)

@@vacuumforming Thanks for answering, I am referring to the air injected before thermoforming, the pre-inflation for tall molds, that air that is injected before vacuum, is it cold air? Doesn't the plastic cool?

@@matiasvaldivieso1293 In fact, vacuum forming is a process of heating and softening a flat sheet, and then molding it through a mold. During vacuum forming, the heat is first softened, and then hot air is blown from below to bulge the sheet so that the formed product can be obtained more uniform size. After the vacuum forming is completed, the cooling system above will emit cold air to help the molded product to be shaped faster and more stably.

Firstly, we need charge the 3d drawing if you don't have the drawing, then the mold cost and samples cost. after confirmed the samples, then will need massive production cost.

Sliding block aluminum molds are multi-component structures designed to move in relation to each other. They feature a primary forming surface and supplementary sliding blocks that facilitate the creation of complex elements such as undercuts, side features, or recessed areas- something a basic one-piece mold can’t achieve.

@@vacuumforming great!! Thanks por You answer mi friend

my pleasure :)@@matiasvaldivieso5629

because this product is quite deep draw, so we use bluge process, it is used in some products with more than one side or right-angle side or products with a small draft angle, its purpose is to reduce the shrinking marks caused by the violent shrinkage of the material, or to solve the problem of the thickness deviation of the product at different positions due to the stacking of the material, the thickness can be more uniform.

@@vacuumforming So do you inflate with heat or compressed air? I think if the compressed air is afraid it will cool the material. You probably have to blow hot air, right?

yes,we do blow hot air,cannot use cold air, it will affect heat the material and softness, then the quality will be a problem.@@mayhutnoi

@@vacuumforming Thank you very much. Wishing your company success and strong development.

Thank you :)@@mayhutnoi
