Got the order in one day
I received a vulcanizing machine inquiry from a Swiss customer on Wednesday, and the customer was very clear about the product they wanted.
After receiving the customer's inquiry, we also respond to the customer in a timely manner to confirm the style and quantity with the customer. However, the customer's specifications and requirements for the product are not very clear, but they have always required the heating temperature to inform us of the heating temperature. However, it is explained to customers that the current temperature used in the market is this heating temperature. If it is too high, it will vulcanize the tire, which is not good for the tire. Customers find it justified. Immediately hit the iron pipe customer address, and promptly consult the freight to quote the freight. The customer did not dispute. Strike again, issued the invoice directly and urged the customer to pay. Tell the customer that if payment is made within the next two days, we can arrange the production. We can deliver the goods directly if there is a courier, and you want to receive the goods early.
Just a few hours after our discussion, the customer called the money. The order was finalized within a few hours!
Attention should be paid to the curing machine during curing
First, the temperature during vulcanization
The vulcanization temperature determines the degree of vulcanization uniformity. Experience and tests have shown that when the temperature is higher than 10 ° C, the vulcanization time will be shortened by about half, and rubber is a poor thermal conductor. The vulcanization process of the product will vary depending on the temperature of each part. Vulcanization effect, the temperature control of thick rubber products is very critical, should gradually increase the temperature, the principle is low temperature for a long time. The heating plate of the blue aurora vulcanizer not only saves electricity, but also has an automatic temperature control system, which effectively improves the quality of product vulcanization.
Second, the amount of sulfur
The greater the amount of sulfur in the heating plate of the vulcanizing machine, the faster the vulcanization speed and the higher the vulcanization process. However, the solubility of sulfur and rubber is limited, and it is not necessarily that the greater the amount of sulfur used, the better the excess sulfur. It will precipitate from the rubber surface. This phenomenon is called "sulfur spraying". To reduce the occurrence of sulfur spraying as much as possible, the method is to add an appropriate amount of sulfur at the lowest possible temperature. Generally, the amount of sulfur in the soft rubber Do not exceed 3%, semi-rigid glue is not more than 20%, the amount of pure hard glue is higher, reaching more than 40%.
Third, curing time
The vulcanization time is an important part of the vulcanization process. If it is too short or the vulcanization process is not enough, it is commonly known as "under sulfur:" If it is too long, the vulcanization degree will be too high. It is commonly known as "over sulfur". The best vulcanization effect is commonly known as normal vulcanization.
