The quality of melamine tableware is closely related to the following key process points of melamine tableware.

1. Raw material ratio and ball mill fineness control

The molding of melamine plastic tableware is a physical and chemical change process. From the description of the molding process, it can be known that the quality and weight of raw materials have an important impact on the quality of products.

If the resin content in the raw materials is not enough, or the degree of ball milling of the raw materials is not enough, the raw materials are relatively rough, and the amount of raw materials added is insufficient, the structure of the produced tableware will be relatively loose or there will be obvious defects, and the soy sauce and vinegar in daily life will easily penetrate and hard to remove.

2. Surface printing ink quality control

Since the surface printing ink in the tableware can directly contact the food, the ink that meets the hygiene and safety standards should be selected.

3. Pressing temperature, pressure, and curing time

The cross-linking and curing of melamine-formaldehyde resin is a physical and chemical change process, so certain reaction conditions, such as temperature, pressure, and time, need to be guaranteed.

The pressure-holding curing time depends on the thickness, type, molding pressure, temperature, etc. of the product. Too long or too short pressure-holding curing time will be detrimental to the performance of the product.

4. Mold finish and exhaust control

The surface finish of the pressed product depends on the rationality of the raw material formula, and the finish of the mold itself is an important factor. Therefore, the finish of the purchased or manufactured mold should be strictly tested and accepted.

If the exhaust is improper, pores will be formed on the surface of the tableware, which will deposit dirt and affect the hygiene of the tableware.

After knowing the importance of these key processes, tableware manufacturers will have more knowledge of melamine raw material, melamine compression moulds or the pressing machine for melamine crockery.

If you have your own quality brand and are committed to the production of high-quality melamine tableware, it is very helpful to find a supplier who values quality as much as you.

Shunhao Machines and Moulds Factory could be your trusted partner, he can help you develop your business, not only provide you with quality products but also experienced service in the melamine tableware production industry.
