Throughout today's graphite mold industry, customer chargebacks due to the extension of delivery dates emerge one after another, which undoubtedly increases the loss of enterprises, and dealers are also sandwiched between manufacturers and customers, which is very helpless and difficult and even leads to many contradictions.

It can be seen that the problem of delivery time is an important factor affecting the development of enterprises. According to people in the industry, there are two main reasons for slowing down the delivery time, production time delay and logistics level constraints. Meanwhile, logistics is no longer a big problem due to the increasingly convenient transportation in recent years. The real reason affecting the delivery time is that the product production time is too long. Then, how to shorten the delivery time of the top ten domestic graphite mold brands.

1. Establish reasonable performance management

In addition, graphite mold should also be unique in enterprise management. Through scientific and reasonable performance management, the power of the enterprise can be improved, and employees are encouraged to put forward suggestions or opinions so that the enterprise can be better improved. An operator of the top ten brands of graphite mold said: "our employees put forward good opinions, and the enterprise will choose them. If we can make some useful small inventions, the enterprise will also help us apply for a patent and give us a bonus, so we often gather together after work to comment on how to complete the rated operation faster and better".

2. Formulate scientific production process

According to experts, the production process of graphite mold includes accepting orders, scheme process, workshop production, debugging packaging, distribution, and delivery. Therefore, in the scheme process of graphite mold, the production batch, selection of production workshop, acquisition of raw materials, customized data entry, installation and commissioning of graphite mold before leaving the factory, recognition, and packaging, logistics allocation, etc. each item has clear provisions on the starting time and completion time, as well as the detailed rules of the specific implementation scheme. This makes the connection between each link faster, and there is no need to inform the operation unnecessarily in the connection.

3. Upgrade skills and improve production power

It is understood that some of the top ten domestic graphite mold brands choose advanced brands. When entering the market, they bring imported graphite mold production equipment, digital graphite mold R & D, and design engineers and their foreign experienced skills. Together with a graphite mold, we also actively update the latest CNC production equipment. Advanced production equipment speeds up the production speed. Experienced engineers and sophisticated skills greatly reduce the probability of errors in the production process of graphite molds.

In recent years, consumers have had higher and higher requirements for power, which is a great challenge for custom graphite molds. But for a long time, challenges and opportunities coexist in the graphite mold industry. Reducing the delivery time will also become the key to the progress and competition of the top ten graphite mold brands.

A good mold manufacturer must have its perfect project development and design process. The following is to share the project development process with you:

1. quotation - comprehensive evaluation shall be conducted according to the product pictures issued by the customer, and reasonable quotation shall be given

2. purchase order issued by quotation confirmation

3. Design & Engineering

4. design check & Review

5. design approval

6. mold construction

7. mold testing & Improvement

8. mold approval

9. final mold test

10. trial production sampling

11. delivery

Continuous casting graphite mold has good high-temperature resistance, its performance is still stable at high temperature, and the amount of heat rise and cold shrinkage is very small, which can be ignored; Graphite has good lubricity, and liquid metal is not easy to adhere to the mold during solidification. It has the characteristics of good thermal conductivity, good wear resistance, and high mechanical strength.

Continuous casting graphite mold is mainly used for continuous casting of copper aluminum, platinum, gold, silver, other non-ferrous metals, steel, stainless steel, etc.

During the use of the mold, the traction speed will have a certain impact on the selection of materials. The faster the traction speed, the higher the requirements for materials. In the communication with customers, the traction speed of customers can be confirmed to facilitate better judgment and select more appropriate materials.

The surface of cast copper mold can also be coated. The main purpose of coating treatment is to improve the oxidation resistance of materials and prolong the service life. Generally, the service life of cast copper mold is about 2-3 days. After coating, the service life is twice as long; The disadvantage of coating is that it will affect the heat conduction performance of the mold. Therefore, normal red copper, brass, and oxygen-free copper are not suitable for coating, while alloy copper needs coating treatment.

According to the casting method, it can be divided into horizontal continuous casting mold or vertical (upward) continuous casting mold.

Nowadays, mold is the basic process equipment used in industrial production. The mold industry is the basic industry of the national economy. Now everyone is looking for a better material to replace the old mold material. Graphite mold just fills the gap of the old material with its various excellent properties. How should we use graphite mold correctly?

1、 Impregnation tank

（1）Prepare the impregnation tank according to the size and specification of graphite products;

（2）The materials for making the impregnation tank need to meet the following conditions: good sealing, acid corrosion resistance, durability, and hardness.

2、 Impregnation solution

Pour about 10cm antioxidant impregnation solution covering the graphite mold into the impregnation tank.

3、 Vacuum impregnation

Soak the graphite mold in the impregnant for about half an hour (room temperature, atmospheric pressure). If you want to improve the antioxidant effect, you can use the following methods: decompression impregnation. Objective: To make the impregnant penetrate into the pores of the product better. But this requires vacuum impregnation equipment.

4、 Air dry

After impregnation, please put the products in a ventilated place for about 2 to 3 days and let them dry naturally.

5、 Brushing

In view of the small number of graphite molds, Xiaobian suggests that you adopt the brushing method.

（1）When painting, please try to slow down the pace, so that the impregnation solution can penetrate into the pores of the graphite mold more fully;

（2）Brush the graphite rotor antioxidant evenly on the surface of the graphite rotor for 2 to 3 times.

The development of graphite mold technology can improve product design and manufacturing efficiency, shorten the production cycle and improve product qualification rate. It has played a great role in promoting China's scientific and technological and economic strength.
