Press Plates Engineered for Automotive, Appliance & Electronics Stamping

Stop waiting 10-12 weeks for press plates that wear out in 2 years. We deliver custom alloy steel bolster plates (42CrMo4, H13, 4140, 4340) with 30% thicker reinforced design, precision ground to ±0.02mm/m flatness, and 45-52 HRC surface hardness – all at a competitive price. In-house steel stock means no raw material delays.

Typical applications: Automotive body panel stamping, washing machine drum forming, electronics enclosure stamping, and hardware component pressing.

Q1: What is the typical lead time for a custom press plate?

A: Standard lead time is 4-6 weeks for custom-sized press plates. Industry average is 10-12 weeks. Rush orders can be delivered in 15-20 days depending on size and material availability. We maintain in-house steel stock for common grades to eliminate raw material waiting time.

Q2: What material grades do you recommend for press plates?

A: The most common grades are 42CrMo4 (4140) for general stamping applications and H13 (1.2344) for high-temperature or high-wear applications. Other options include 4340, 17-4PH stainless, and carbon tool steels. We help you select the optimal grade based on your stamping tonnage, cycle rate, and part material.

Q3: What flatness tolerance can you achieve?

A: We guarantee ±0.02mm per meter flatness after precision grinding. Standard industry tolerance is ±0.1mm per meter. Tighter tolerances (±0.01mm/m) are available upon request for high-precision applications such as electronics or automotive critical surface stamping.

Q4: What is the maximum size press plate you can manufacture?

A: Our maximum single-piece capacity is 2,500mm × 1,500mm (98″ × 59″) with thickness up to 300mm (12″). Larger sizes can be manufactured as segmented plates or bolted assemblies. Maximum weight capacity is 15 tons per single forging.

Q5: How long will a Ningshing press plate last compared to competitors?

A: Our press plates typically last 5+ years under normal stamping conditions. Competitor plates often need replacement every 2-3 years. The extended life comes from our 30% thicker reinforced design, premium alloy steel, and precision heat treatment achieving 45-52 HRC surface hardness.

Q6: What quality documentation do you provide with each press plate?

A: Each press plate ships with a complete quality dossier including:

• Material mill test certificate (chemical composition)
• Heat treatment record (time-temperature curve)
• Hardness test report (per piece)
• CMM flatness and dimensional inspection report
• Ultrasonic testing (UT) report (if specified)
• ISO 9001:2015 certificate of compliance

Third-party inspection (SGS, BV, TÜV) is available upon request.
