Usually, products that have just been developed or designed need to make industrial rapid prototypes. Industrial rapid prototypes is the first step to verify the feasibility of the product. It is the most direct and effective way to identify the defects of the designed products, so as to improve the product. At this point, it is usually necessary to conduct a small amount of trial production and then find out that there is insufficient improvement in the batch. The products that are designed and completed cannot generally be perfect or even unusable. If there are defects in the direct production, all of them will be scrapped, which will waste human and material resources and time. The general situation of the industrial rapid prototype is a small number of samples, the production cycle is short, and the manpower and material loss is small. Quickly find out the insufficiency of product design and improve it, and provide sufficient basis for the product's setting and mass production. Deluxe Company specializes in industrial rapid prototypes processing and is committed to providing perfect products to help customers quickly complete design and testing, and open the market as soon as possible.

Is Melamine Foam Safe Thanks to an absurd little rumor circulating widely on the internet, many people are questioning whether their favorite magic eraser cleaning tool is actually harmful and whether the product is safe to use. Many people consider that this product contains formaldehyde, but the truth is that melamine does not contain formaldehyde. The myth that magic block sponge is toxic has been debunked, and this should be your first stop if you read anything online about whether or not melamine is toxic. When used as directed, rest assured that the melamine foam pad is safe and will not pose a health hazard or safety concern. After all these years, the melamine foam sponge ingredient has been used safely and widely in a variety of household items. The melamine foam sponge is also non-toxic to the environment. The melamine foam sponge is non-toxic, so it is very suitable for household cleaning and has been well-received by most people. Formaldehyde is not a factor in melamine foam sponges and never has been. The properties of this new chemical are different from their composition. That's what was said in a widespread internet rumor from a few years ago about the magic block sponge, which massed on the toxic chemical formaldehyde, which most of us associate with the smell of frogs waiting to be dissected in science class. As we learned in high school chemistry, when you mix different chemicals, the resulting compound is more than the sum of its parts. Melamine foam sponge (formaldehyde-melamine-sodium bisulfite copolymer) contains an element in its chemical name, the word formaldehyde. However, this element is not formaldehyde and does not cause a risk to health or safety. You can think of the name as sodium chloride, which is table salt. Sodium itself can be harmful, but it is safe to use sodium chloride salts. None of the materials in the melamine foam sponge have received any health-related labels. magic eraser does contain a substance called formaldehyde-melamine-sodium bisulfite copolymer, but this, unlike formaldehyde, does not pose a health or safety risk. However, nano cleaning sponge erasers are abrasive, so you don't want them rubbing against your skin or your kids grabbing at them. Formaldehyde may be present in trace, trace amounts due to the manufacturing process. Be that as it may, the amounts present are well below the standards set by government agencies and industry associations, and are lower than levels found in indoor air. So we don't seem to have to worry about the eraser emitting toxins during use.
