Professional Technical Q&A

What thickness of material can be processed on a K span roll forming machine?

Our K Span Roll Forming Machine handles materials from 0.4mm to 1.8mm thickness depending on model. The 600-305 model processes 0.4-1.5mm galvanized steel or aluminum, while the 914-610 handles up to 1.8mm. Material hardness should not exceed HRB 85 to prevent premature roll wear.

What safety standards govern K span machine installation?

All installations must comply with ISO 12100 (Risk Assessment) and ISO 13849 (Safety Control Systems). Additionally, electrical components meet IEC 60204-1 standards. Our machines incorporate Category 3 safety circuits, dual-channel emergency stops, and mechanical guarding per ANSI B11.8-2021 specifications.

How does roll diameter affect forming quality?

Larger diameter rolls (minimum 80mm for primary stations) reduce material stress and improve surface finish. Our design uses progressive sizing: entrance stations feature Ø80mm rolls for initial forming, while finishing stations utilize Ø120mm rolls to minimize springback and achieve tighter tolerances (±0.5mm).

What maintenance schedule do these machines require?

Critical maintenance includes:
• Daily: Gearbox oil level check, roll surface cleaning
• Weekly: Bearing lubrication (NLGI 2 lithium grease), cutter alignment verification
• Monthly: Hydraulic system inspection, gear backlash measurement
• Annually: Complete roll station calibration and gearbox oil replacement

What material specifications are optimal?

We recommend:
• Galvanized steel: G550 Z275 coating (min yield strength 550MPa)
• Aluminum: Alloy 3004-H16 (tensile strength 190-230 MPa)
• Pre-painted steel: PVDF coatings with minimum 25μm thickness for durability

How many forming stations are necessary?

The complex geometry of K-span profiles requires 18-22 forming stations. Our 600-305 model utilizes 20 precision stations - 8 for preliminary forming, 6 for intermediate shaping, 4 for profile locking, and 2 finishing stations. This progressive approach minimizes material stress and optimizes dimensional accuracy.

What production speeds can be achieved?

Standard production speeds range 20-28 meters/minute depending on material thickness and profile complexity. Thinner materials (0.4-0.6mm) run at 25-28 m/min, while heavier gauges (1.2-1.5mm) operate at 18-22 m/min. Maximum efficiency occurs at approximately 80% of rated speed to account for material variations.

Industry Recognition & Technical Validation

"The efficiency gains from modern roll forming technology represent the most significant advancement in metal fabrication since CNC technology. Particularly in large-span applications, YOWIN-class machines demonstrate 23-35% energy savings versus conventional systems." - Journal of Advanced Manufacturing Systems (2023)

A recent technical evaluation by the International Association of Structural Engineers concluded: "Contemporary big span roll forming machine systems achieve dimensional tolerances previously thought impossible in high-speed production. The mechanical stability of profiles produced on such equipment meets AISI S100-16 structural standards for industrial buildings."
