The company has established a complete quality control system. The company implements a market-oriented operation of quality inspections for all employees and mutual inspections between each process. Established a strict quality control system, implemented international quality system standards, adopted production standards far higher than industry standards, and internal control standards exceeded national standards. The raw material procurement standards are almost harsh, and the wood is mainly American red maple, red oak, and North American cherry. The company (the first in the Northeast) introduced a high-frequency electronic drying cellar for secondary drying to balance the moisture content to ensure product stability. The paint adopts Italian SAYERLACK (style and Li) and Dutch AKESU (Akesu) paint. The plate procurement standard is upgraded from the international E0 grade plate to formaldehyde-free plate

The wood selected by Longze Weini is imported wood, and the moisture content of the wood is strictly tested, and the wood is balanced through the drying cellar, so that the moisture content is strictly controlled between 8%-12% to ensure that the product structure is stable and not easy to crack and deform . In order to better interpret the natural texture and original beauty of solid wood products, the paints we currently use are Shierli Paint and China Resources Paint produced in Italy. In order to ensure that the product has a thin paint film, a delicate hand feel and good transparency, the company uses a dust-proof water curtain and a dust-free spray booth to combine the operating space, as well as manual and automatic wide-profile surface grinding machines to ensure product quality. Each strict and demanding production process makes its products meet the national health and environmental protection standards.
