Frequently Asked Questions

Find answers to common questions about our hydraulic press products, customization options, quality assurance, and after-sales service.

Product & Specifications

What is the tonnage range of YueDa hydraulic presses?▼

Our standard product range covers 10 to 5,000 tons. The hydraulic press series spans 10-5,000 tons, the oil press series covers 50-3,000 tons, and the trimming press series ranges from 10-1,000 tons. For requirements outside these ranges, we offer fully custom solutions.

What precision can your presses achieve?▼

Our hydraulic presses achieve position repeatability of ±0.01mm, stroke accuracy of ±0.005mm, and pressure accuracy of 5‰ of full scale. These specifications are verified on every machine during 72-hour load testing.

What is the difference between a hydraulic press and an oil press?▼

Both use hydraulic principles, but they differ in application focus. Hydraulic presses are general-purpose machines for forming, stamping, and drawing operations. Oil presses are optimized for specific processes like die casting trimming, plastic compression molding, and rubber vulcanization.

Do you offer servo hydraulic presses?▼

Yes. Our servo hydraulic press series uses servo motor-driven pumps instead of conventional constant-speed motors. This delivers up to 70% energy savings, lower noise levels, faster cycle times, and more precise control. Servo models are available across our full tonnage range.

Customization & Ordering

Can you customize presses to our specific requirements?▼

Absolutely. Customization is one of our core strengths. Our 6-person R&D team with 10+ years of experience can design non-standard equipment based on your tonnage requirements, workpiece dimensions, process parameters, automation level, and production environment.

What is the typical lead time for standard and custom presses?▼

Standard models: 30-45 days. Custom designs: 60-90 days depending on complexity. For urgent requirements, we can discuss expedited manufacturing schedules.

What information do you need for a custom quote?▼

We typically need: (1) workpiece material and dimensions, (2) required pressing force and stroke length, (3) production volume and cycle time requirements, (4) precision specifications, (5) automation requirements, and (6) any special environmental or safety requirements.

Quality & Testing

What quality certifications do you hold?▼

We are certified to ISO 9001:2015 quality management system standards. Our products also carry CE marking for European market access. Additionally, we hold multiple invention and utility model patents for our proprietary hydraulic system designs.

How do you ensure quality on every machine?▼

Every machine passes through our five-stage quality control process: (1) Incoming material inspection, (2) In-process quality control with CMM verification, (3) Assembly verification, (4) 72-hour continuous load testing, and (5) Final acceptance with complete documentation.

Can we witness testing before shipment?▼

Yes, we welcome customer witness testing. You or your representative can visit our facility in Dongguan to observe the full load testing process. We also support remote video witnessing for international clients.

Service & Support

What after-sales service do you provide?▼

We provide: 24-hour response guarantee, 48-hour on-site repair for domestic clients, remote technical support for international clients, spare parts supply with guaranteed availability for 10+ years, and annual maintenance inspection programs.

Do you provide installation and training?▼

Yes. Every machine purchase includes on-site installation, commissioning, and operator training. We typically provide 3-5 days of on-site training per machine, with additional training available upon request.

Do you serve international customers?▼

Yes, we actively serve customers in 20+ countries across Southeast Asia, Middle East, South America, and Africa. We provide English-language documentation, remote technical support, and can arrange on-site service for international installations.
