At present, the methods often used to select mesophase carbon microbead drying equipment manufacturers are as follows:

1, intuitive judgment method

Intuitive judgment method refers to a method of selecting the manufacturer of mesophase carbon microsphere drying equipment through investigation, consultation, comprehensive analysis and judgment. It is a subjective judgment method, mainly to listen to and adopt the opinions of experienced purchasing personnel, or to make judgments directly by purchasing personnel based on experience.

The quality of this method depends on the mesophase carbon microsphere drying equipment manufacturers information is correct, complete and decision-makers analysis and judgment ability and experience. This method is simple and fast to operate, but it lacks science and is limited by the level of detail of the information available.

2. Assessment and selection method

On the basis of full investigation and understanding of the intermediate carbon microbead drying equipment manufacturers, the method of selecting suppliers is carefully examined, analyzed and compared. The investigation of mesocarbon microbead drying equipment manufacturers can be divided into preliminary investigation and in-depth investigation. The selection of preliminary survey objects is very simple, and the basic basis is the variety and specification, quality and price level, production capacity, transportation conditions, etc. In these conditions suitable for the mesocarbon microbeads drying equipment manufacturers selected several, is the object of preliminary investigation.

The selection of in-depth investigation objects is to conduct in-depth research and inspection on these mesophase carbon microbead drying equipment manufacturers. The selection criteria are mainly the strength of the enterprise, the production capacity of the product, the technical level, the quality assurance system and the management level.

Through the trial operation stage, after obtaining the comprehensive results of each mesophase carbon microsphere drying equipment manufacturer, the manufacturer can basically be determined.

3. Bidding selection method

When the purchase quantity is large and the market competition is fierce, the bidding method can be used to select the mesophase carbon microbead drying equipment manufacturer. The purchaser, as the tenderer, puts forward the conditions and requirements of the procurement in advance, invites many manufacturers of mesophase carbon microsphere drying equipment to participate in the bidding, and then the purchaser in accordance with the prescribed procedures and standards one-time selection of the transaction object, and put forward favorable conditions of the bidder to sign the agreement and other processes. note that the whole process requires openness, fairness, and merit.

4. Selection through negotiation

In the optional intermediate phase carbon microsphere drying equipment manufacturers more, the procurement unit is difficult to choose, can also use the negotiation selection method, that is, by the procurement unit to select the supply conditions are more favorable manufacturers, with them to negotiate separately, and then determine the appropriate manufacturers.

Compared with the bidding selection method, the negotiation selection method is more guaranteed in terms of product quality, delivery date and after-sales service because the two parties can fully negotiate, but due to the limited range of choices, it may not be possible to choose cheap manufacturers with favorable supply conditions. When the procurement time is more urgent, the bidding unit is less, the manufacturer competition is not fierce, the order material specifications and technical conditions are more complex, the negotiation selection method is more appropriate than the bidding selection method.
