1. What is the Rainbow High-Speed Cold Heading Screw Machine?
A cold heading machine designed for high-speed forming of fastener blanks from wire. It uses crankshaft-and-connecting-rod automation and dedicated dies to produce a wide variety of semi-finished screw and fastener heads for downstream processing.
2. Which materials can this machine process?
It can cold-head common fastener metals such as carbon steel, stainless steel, aluminum and copper, using appropriate dies and process settings for each material.
3. What types of fasteners can it produce?
The machine can form many head types including truss, countersunk, set screws, wood screws, chipboard and self-tapping screws, flat/hex/pan/socket/button heads and more, depending on tooling.
4. What are the available models and how do I choose one?
Multiple models are offered (RSH3, RSH4, RSH5, RSH6, RSH8, RSH10, RSH12, RSH16, etc.), each differing by maximum blank diameter/length, stroke and output. Choose based on the maximum blank size, required output rate and the blank length your application needs.
5. What production rates can I expect?
Output depends on model and part geometry; typical ranges across the product line are approximately 25 to 200 pieces per minute. Smaller parts and higher-speed models yield the top rates.
6. What blank sizes and lengths are supported?
Depending on model, the machines support approximate blank diameters from about 3–16 mm and blank lengths from short cutoffs up to around 450 mm. Exact limits depend on the chosen model—refer to the model specification table for details.
7. What power, size and weight considerations should I plan for?
Main motor power varies by model (roughly 1.1 kW up to around 22 kW/25 HP). Machine footprints range from about 1.4×0.75×0.9 m to 6.5×2.25×2.1 m and weights from roughly 650 kg up to ~21,000 kg depending on model. Check the specific model datasheet before installation planning.
8. How does the machine handle tooling (dies/cutters) and changeover?
Forming is done with main dies, punch dies and cut-off dies sized to the part. Dies and cutters are replaceable; changeover involves removing and installing the appropriate die sets. For complex changeovers or custom heads, the manufacturer can supply or machine the required tooling.
9. Does the machine produce finished screws or semi-finished blanks?
It produces semi-finished blanks (headed and cut to length). Secondary processes such as thread rolling, heat treatment and surface finishing are typically required to make final functional screws.
10. Can the cold heading machine be integrated with my wire rolling line?
Yes. These machines are designed to operate in conjunction with automatic wire rolling/feeding equipment. The manufacturer can advise on compatible feeders and integration for continuous operation.
11. What safety features and operator protections are provided?
The product overview notes safety measures are in place. Standard protections typically include guards, emergency stop, interlocks and recommended safe operating procedures. Confirm exact safety features for the model you purchase and follow local machine-safety regulations.
12. What maintenance is required and are spare parts available?
Routine maintenance includes lubrication, periodic inspection of dies, punches and cutters, and checking fasteners and bearings. The manufacturer provides spare parts and technical support—keep critical spare dies and cutters on hand to reduce downtime.
13. Can the machine be customized for special fastener designs?
Yes. The machine output can be customized via special tooling and process parameter adjustments. For unique head forms, sizes or nonstandard materials, consult the manufacturer for tooling design and feasibility.
14. What technical support, installation and training services are available?
The manufacturer offers support and assistance, including help selecting the right model, installation guidance, commissioning and operator/maintenance training. Contact them to arrange on-site or remote support options.
15. How do I get pricing, lead time, warranty and after-sales details?
Pricing, lead time, warranty terms and after-sales service vary by model, configuration and region. Contact the manufacturer or authorized distributor with your part specifications and production requirements to receive a tailored quote and delivery schedule.
