300-Ton Rapid Stretching and Forming Four-Column Hydraulic Press

High-quality round steel is polished and processed with an external cylindrical grinder, then surface plated with hard chrome to ensure hardness and smoothness. The columns undergo medium-frequency quenching, significantly enhancing hardness, reducing damage during operation and transportation, and extending service life.
The lower surface of the sliding beam and the upper surface of the worktable are sequentially rough-milled by a large floor-type milling machine and then finish-milled by a CNC gantry milling machine to ensure the surface flatness and parallelism, thereby guaranteeing the precision of product forming.

Both the worktable and the sliding beam are equipped with T-slots for convenient and rapid installation and replacement of molds.

The worktable is equipped with an ejection rod for convenient demolding after the pressing process.

The electrical control box is equipped with a hydraulic pressure gauge on its surface for convenient monitoring of the pressure during the hydraulic machine's operation. Inside, it is fitted with a PLC device, which, when programmed, can automate the production process of the hydraulic machine.
The stroke control switch allows for fixed-distance movement of the hydraulic machine's sliding beam, eliminating the need for a complete pressing cycle, thereby increasing production efficiency.

1. Am I able to get the necessary documents?
Absolutely, we supply a range of documents including Certificates of Analysis/Conformance, insurance details, certificates of origin, and other key export documents.
2. What is your standard lead time?
We usually require about 30 days for samples and between 30 to 60 days for mass production after the deposit is paid. Our lead times commence upon receipt of the deposit and final product confirmation. If our lead times don't align with your timeline, please discuss this with your dedicated sales representative. We aim to meet your needs whenever possible.
3. Which payment options do you offer?
We accept payments via bank transfer, Western Union, or PayPal. Our typical payment terms involve a 30% initial deposit, with the remaining 70% due when the bill of lading copy is presented.
4. What is included in the product warranty?
We stand behind the quality of our materials and craftsmanship. Even after the warranty period, we make an effort to address and fix any issues to ensure customer satisfaction.
5. Can you ensure the secure transport of the products?
Definitely, we use robust export packaging to ensure safe delivery. We use specialized packaging for hazardous materials and employ certified cold chain shippers for items that require temperature control. However, any unique packaging needs may incur extra costs.
6. How are the shipping costs calculated?
The shipping costs depend on the chosen method of delivery. Express shipping is faster but more expensive, while sea freight is often the better option for larger orders. We can provide precise freight quotes once we have the specifics of your order, such as quantity, weight, and your preferred shipping method. Feel free to contact us for more details.
