Floating Seal Assembly



Why we run this business and website
- Although the price of our competitors’ products is very low, but the quality is very poor, overseas buyers are tired of this kind of low-quality products, and because we optimize the process better, we take care of our quality colleagues, and the production cost is lower, so we set up our business Almax Seal Solution.
- We have been launching the B2B platform before, but the effect has declined seriously in recent years, so we need to do a website to market and sell goods.
How do we work with our clients
- We are in the wholesale business, because the value of the goods is low and the order quantity is usually small, so it is easy for customers to make purchasing decisions after seeing the products on the website.
- Customers first browse the website, and then send us an inquiry by filling out the form on the website. after our salesman gets the purchase information, he will quote to the purchaser, and after both sides confirm all the transaction details, we will send samples to the customers. after the user is satisfied with the sample, he will give us the final order.
- After the factory has finished producing the goods, it will be delivered to the customer’s country by sea, air and express delivery.
