I. look at the manufacturer's planning and production ability:

　　1. Planned manufacturers pay more attention to word-of-mouth and credit, and will not take the risk of shoddy goods and shoddy work and materials. Especially when customers do not have a special understanding of products, they advocate on-site investigation.

　　2. Planned manufacturers are more cautious and strict in the acquisition of raw materials. As a sandwich panel industry with not too high skill content, the quality of raw materials directly affects the quality. For example, the density of rock wool used for rock wool drying board and clean room purification board must be more than 80K to ensure the strength of thermal insulation text. Most people have no concept of this and can only rely on the manufacturers to consciously control it.

　　3. Manufacturers with strong production ability can basically use special machines. One model can only produce one plate type, and the quality is relatively stable.

II. Check whether the manufacturer's production process is perfect and whether the process is refined:

　　1. As a continuously produced product, only when it is standardized and standardized, with the assistance of the team, each employee has a clear division of labor, understands the factory specifications of the products, and is guaranteed by written system documents, can we continuously accumulate and make progress and produce products with stable quality.

　　2 . Taking glass magnesium sandwich panel as an example, the main process is: preparation of glass magnesium plate - & gt; Cutting of glass magnesium plate - & gt; Pressing of glass magnesium shelf - & gt; Polishing of shelf surface - & gt; The composite of steel plate and core material is normal. If a factory can complete all the above processes, the glass magnesium plate produced will basically have no major problems. Practice has proved that the lack of any of the above processes will leave serious hidden dangers. For example, the lack of surface grinding will affect the bonding strength, and the sandwich plate will be degummed and blistered over time.

III. check whether the raw material inventory of the manufacturer is sufficient:

Sandwich panels have a wide range of specifications and high requirements for raw material inventory, such as steel coils, rock wool with different densities, glass magnesium flat plate, magnesium oxysulfide, etc. only when they have sufficient inventory can they be delivered on time within 3 days and replenished on time in the later stage, which will not affect the project progress. In particular, for the raw material inventory of rock wool drying board, it is necessary to have a certain safety inventory for all thickness color coated board, galvanized board and rock wool scale.

IV. check whether the manufacturer's product series and supporting facilities are complete:

There are three categories of sandwich panel services: purification engineering, coating engineering and steel structure roof. Powerful manufacturers can basically cover the whole product series, which is not only the embodiment of skills and talents, but also the guarantee of customer supply ability. Any project will involve the simultaneous use of several plates. Even some manufacturers have begun to provide "one-stop purchase" services, such as not only producing plates for purification engineering, It also produces purified doors and windows, purified aluminum, and provides hardware supporting facilities, which not only provides convenience to customers, but also saves acquisition time and cost for customers.

V. check whether the manufacturer has a professional after-sales service team and team:

In today's increasingly fierce competition for product homogenization, after-sales service is very important. In the past, the form of taking orders by yourself, following orders, delivering goods and after-sales is obviously insufficient, and can not adapt to the development of the industry. Powerful manufacturers have their own after-sales team and distribution team, which can deliver goods at any time with low cost and flexible closing and replenishment. In case of special circumstances on the construction site, one-to-one specialists provide services or even on call, so as to ensure the progress of the project.
