Seallon`s self-developed ERP system can realize efficient production management, optimize production processes, and reduce production costs.

1. Make detailed records of warehouse entry and exit operations in the system, clarify the capacity of each material(semi-finished product or product, etc);

2. The system can associate the company's sales order with the factory's production plan and disassembled production tasks. The completion of each production work order is updated in real time. Workshop management can check the progress of the production work order at any time and give timely feedback to the sales department.；

3. Through the system, production tasks are issued and queried clearly and quickly. Production workers can automatically report on a daily basis. The results of the report are approved by the workshop director or quality inspector. After the approval is passed, the production progress will be automatically updated.

First Product Inspection and Materials & Measurements Inspection

Varieties of Inspection Methods

We can be as professional as a third-party inspection company. In addition, we are responsible for the inspection results immediately and directly

We generally conduct shell tests of valves and accessories, upper sealing tests, sealing tests, opening and closing tests, final appearance and packaging inspections, etc.

If there are special requirements, finished product can be cut to make physical & chemical tests. The inspection records and image data will be collected and reported to the customer.

Qualified products will be admitted to the area to be shipped, and unqualified products will be handed over to the production department for rework or reproduction, which will be shipped after passing the inspection.
