HT300 Cast Iron D16 3D Welding Table Stable For Batch Welding Production

Our HT300 Cast Iron D16 3D Welding Table is engineered to solve your core pain points: platform warpage, inconsistent workpiece dimension and frequent fixture replacement.

Different from ordinary carbon steel tabletops, this 3D welding table adopts high-strength HT300 pearlite grey cast iron with double stress relief treatment. Equipped with industry-standard D16 (Φ16mm) 50*50mm grid holes on five sides, it supports full 3D clamping, positioning and assembly. Compatible with all universal D16 accessories, it perfectly fits manual welding and robotic automated batch welding lines, greatly cutting fixture costs and improving production consistency.

• Premium HT300 Cast Iron Material: Tensile strength ≥300MPa, HB180-240 hardness. Inherent damping & ultra-low thermal expansion to avoid heat deformation during long-time welding cycles.
• Double Stress Relief Process: Adopts high-temperature annealing + vibration aging treatment to eliminate internal casting stress permanently, zero deformation for lifelong batch production.
• 5-Sided D16 Standard Hole System: Precision H7 tolerance Φ16mm holes with 50×50mm matrix spacing (tolerance ±0.05mm). Top & four side walls fully perforated for omnidirectional 3D workpiece clamping.
• Hardened Nitrided Surface: Plasma nitriding treatment forms 450-630HV hardened layer, anti-slag, anti-scratch and high-temperature resistant, drastically reduce daily maintenance frequency.
• 100% Modular & Interchangeable: Compatible with global standard D16 fixtures (locating pins, clamps, supports, angle boxes). Fast changeover for multi-type small-batch production.
• High Precision and Strong Load-bearing: Flatness up to 0.1mm/㎡ (0.05mm/㎡ for robotic version), repeat positioning accuracy ≤0.02mm; single table load up to 2 tons, support multi-table splicing for oversized workpieces.

This D16 3D welding table is specially optimized for high-volume batch production scenarios, solving common pain points of traditional welding platforms:

Stable casting benchmark and anti-deformation performance eliminate size deviation caused by platform deformation, reduce defective rate effectively.

Modular fixtures can be disassembled and rearranged in 10-15 minutes, shorten downtime during product switching, perfect for mixed small-batch production.

Nitrided hardened surface resists welding spatter and impact damage, no frequent polishing or surface repair needed, extend service life up to 8-10 years.

Suitable for manual arc welding, MIG/TIG welding, and can be directly matched with robot positioners to build automatic welding workstations.

All accessories are 100% compatible with D16 hole system, one-stop procurement available:
