Complete Powder Coating Lines for Metal Products

Manual Lines: Operators manually move parts from pretreatment → spray booth → oven. Lowest cost ($20K–$40K), best for small batches and high product variety. Throughput: 5–20 parts/hour.

Semi-Automatic Lines: Conveyor system moves parts automatically between stations. Operators spray and monitor. Medium cost ($40K–$80K), good balance of automation and flexibility. Throughput: 20–50 parts/hour.

Fully Automatic Lines: Robotized or fully conveyor-driven with automated spray guns. Highest cost ($80K–$200K+), best for high volume and consistent products. Throughput: 50–200+ parts/hour.

It depends on three factors:

• Volume: 0–100 parts/day → Manual. 100–300/day → Semi-Auto. 300+/day → Fully Auto
• Product Variety: Many different products → Manual/Semi-Auto. Single product → Fully Auto
• Space & Budget: Limited space/capital → Backpack booth or compact system. Larger space/budget → Full-scale line

Quick Assessment: Send us your production volume, product specs, and factory space, and we'll provide a no-cost recommendations.

Yes, absolutely. We design custom layouts for every factory. We can:

• Create vertical spray booth designs for tight spaces (as small as 8 m²)
• Design curved or L-shaped conveyor paths to navigate around existing equipment
• Scale oven sizes up or down (small oven for 2m parts → large oven for 6m+ parts)
• Adjust spray booth height/width to accommodate your specific product dimensions
• Integrate with your existing pretreatment or drying systems

We typically conduct a site visit or review detailed floor plans before finalizing design.

Space requirements depend on line complexity and product size:

These estimates include the spray booth, oven, conveyor, pretreatment (if included), and walkways for maintenance.

Most upgrades are possible without full replacement. Common upgrades include:

• Replace old spray booth with modern recovery system (saves 40% on powder costs)
• Upgrade oven controls to modern PLC for better temperature precision
• Add automated powder supply system for faster color changes
• Install conveyor system to replace manual material handling
• Add secondary recovery cabinets to increase powder savings

Send us photos/videos of your current line, and we'll provide an upgrade recommendation with cost and ROI analysis.

General Rule: A powder coating line becomes profitable at 60–80 production hours per week.

• Backpack Booth: 100–200 parts/week (ROI: 12–18 months)
• Manual Line: 200–500 parts/week (ROI: 18–24 months)
• Semi-Auto Line: 500–1,500 parts/week (ROI: 24–36 months)
• Fully Auto Line: 2,000+ parts/week (ROI: 24–48 months, but per-unit cost is lowest)

Important: Volume less than 100 parts/week typically doesn't justify a full line. Consider outsourcing or shared facility options.

Expected Lifespan: 15–20+ years with proper maintenance.

We provide maintenance training and spare parts support for life of equipment.

Typical Timeline:

• Backpack Booth: 3–4 weeks
• Standard Manual/Semi-Auto Line: 6–8 weeks
• Customized Line with Engineering: 8–12 weeks
• Complex Fully Automatic System: 12–16 weeks

Timeline includes design, manufacturing, quality testing at factory, packing, and logistics to your door.

Rush Options: We offer 50% expedited delivery for additional 15–20% cost.

Currently, we focus on permanent sales, but we can discuss custom arrangements for high-volume, time-limited projects.

Alternative options:

• Competitive lease-to-own financing (we can connect you with partners)
• Subcontracting your coating work to our partner networks in your region
• Temporary toll-coating services while your line is being installed

Interested in a custom arrangement? Contact our sales team to discuss your timeline and volume.

One line can handle multiple products IF they share similar size and coating requirements.

Example – CAN Switch Between:

• Small metal brackets, hinges, and fasteners (all fit spray booth, similar curing time)
• Different colors of powder on same part size (spray booth and oven work the same)

Example – CANNOT Easily Switch:

• Large structural beams (6m+) with small metal hardware (0.5m) – different booth requirements
• Steel parts needing 10 min cure time vs. aluminum needing 5 min – oven conflicts

Pro Tip: Our modular designs allow flexible configurations. Send us your product specs and we'll design a line that covers your range.

Minimum Order Quantity (MOQ): No MOQ for custom coating lines. We build single units as well as multiple systems.

Standard Payment Terms:

• 50% deposit upon order confirmation
• 50% payment upon factory completion + inspection (before shipment)
• Flexible terms available for qualified customers (net 30/60/90 depending on volume)

Financing Options: We can facilitate connections with equipment financing partners for approved customers.

Expedited Timelines Available:

• Rush Manufacturing: +15–20% cost for 50% timeline reduction
• Express Logistics: Air freight (instead of sea) for immediate delivery (additional 25–40% shipping cost)
• Priority Factory Slot: We schedule rush jobs in next available production window

Conditions: Design must be finalized, 50% deposit required, rush fees are non-refundable.

Contact our sales team immediately if you need expedited delivery – we'll assess feasibility and provide firm timeline.
