KT-PUR-1800 hot melt coating laminating machine: maximum material width 1800 mm, machine roller surface 2000 mm, machine speed 0-35 m/min.

Short answer for line engineers and procurement teams: the KT-PUR-1800 is a hot melt coating laminating machine with a maximum material width of 1800 mm and a machine roller surface of 2000 mm, built by JIANGSU KUNTAI MACHINERY CO.,LTD and listed by the manufacturer for safety shoes manufacturing. It applies adhesive through one gluing roller at coating weights from 25 to 110 g/m², runs at 0-35 m/min, and is delivered with a 200 kg glue melter, an oil heater and four sets of trolley with air shaft.

Problem Definition: What a Safety Shoe Line Actually Demands from a Laminator

A safety shoe is a multilayer product. Uppers, linings, padding foams, films and reinforcement fabrics are typically assembled with stitching, adhesive bonding, or a combination of the two. Laminating equipment becomes relevant wherever two or more flexible materials have to be bonded across the full web width with a controlled amount of adhesive, at a speed that keeps pace with the rest of the line.

For a factory evaluating laminating equipment, the decision usually narrows to three measurable questions:

1. Width. Will the widest material you run fit inside the machine envelope, and does the roller surface cover the web you intend to bond?
2. Adhesive control. Can the machine hold the coating weight your bond specification needs, roll after roll and shift after shift?
3. Integration. Can the heating method, the installed capacity and the material-handling configuration be absorbed by your existing line and utilities?

Where those questions are answered poorly, the symptoms show up on the production floor rather than in the datasheet: starved bonds at the edges of wide rolls, adhesive strike-through on thin lining materials, coating weight drift across a shift, and delamination after repeated flexing. This is why an application guide, rather than a specification sheet alone, is the practical starting point for an equipment shortlist.

This guide therefore treats the KT-PUR-1800 as a candidate platform for safety shoe manufacturing and works through the published specifications, the construction and component set, a line-integration checklist, realistic use cases, and the boundary conditions under which another machine family would be the better choice.

Industry Background: Why Hot Melt and PUR Lamination Keeps Expanding

The equipment category is growing. The global laminating machines market is estimated to be valued at USD 786.5 million in 2026 and is projected to reach USD 1,356.7 million by 2033, according to Coherent Market Insights.

The adhesive chemistry behind hot melt coating is expanding as well. The PUR hot melt adhesives market is expected to grow at a CAGR of 7.2% through 2034, reaching USD 7.1 billion, according to Dataintelo. PUR hot melt systems are the adhesive family most commonly associated with the coating and laminating machines used for flexible multilayer assemblies.

Manufacturing capacity for this equipment class remains concentrated in Asia. Asia-Pacific dominated the textile machinery market with a 72.70% share in 2025, primarily led by automation surges in China, according to Fortune Business Insights. For buyers in Europe, North America, South America, South Asia, Africa and the Middle East, that concentration is exactly why supplier evaluation, component transparency and pre-shipment verification matter as much as the headline specification.

Two standards frameworks usually shape the compliance conversation around this type of equipment. Textile machinery safety is governed by the ISO 11111 series; specifically, Parts 2 to 7 cover safety requirements for different machinery types, according to the International Organization for Standardization. Machinery placed on the EU market must additionally satisfy the Machinery Directive 2006/42/EC - the directive under which Kuntai's CE certificate for this machine family was issued.

Solution Fit: How the KT-PUR-1800 Maps to Safety Shoe Manufacturing

Machine Identity and Published Specifications

The KT-PUR-1800 is the hot melt coating laminating machine model in the Kuntai laminating range. Its published specification covers the parameters that most often decide whether a machine can be integrated into an existing production line:

Construction and Component Set

Two construction options are published for the KT-PUR-1800: carbon steel or SS304. The component set is equally explicit - a Siemens motor (made in China), an Inovance inverter and Schneider electric components. For a procurement team, named components matter for two practical reasons: spare-part sourcing over the life of the machine, and the ability of a local electrical contractor to work on the panel without waiting for proprietary parts. It also means the electrical drawing can be reviewed against your own plant standards before the order is placed, rather than after the machine lands.

Adhesive Handling and Coating Control

The adhesive side of the KT-PUR-1800 is built around a single gluing roller specified for 25 to 110 g/m², a 200 kg glue melter and an oil heater, with heating available by electricity or thermal oil. That coating-weight band is wide enough to cover both light bonding of thin lining materials and heavier adhesive application where a foam or padding layer has to be anchored. The 200 kg melter capacity determines how often the adhesive supply has to be replenished during a production run, which in turn affects how the machine is scheduled alongside the rest of the shoe line.

Material Width, Handling and Line Position

The machine's maximum material width is 1800 mm while its roller surface is 2000 mm, and four sets of trolley with air shaft are included for material handling. Whether those numbers are a comfortable fit or an over-specification depends entirely on the widest roll your safety shoe line will ever run, and on whether the machine is intended to serve one narrow product family or be shared across several footwear constructions.

The Manufacturer Behind the Platform

KUNTAI operates a 30,000 m² manufacturing facility with 210 employees and an annual output of 650 units.

JIANGSU KUNTAI MACHINERY CO.,LTD was founded in 1983 and designs and builds coating, laminating, impregnation and cutting machinery for technical textiles and composites, with more than 40 years in the field.

Step-by-Step: A Line-Integration Checklist for Safety Shoe Producers

1. Measure the widest substrate you will ever run. Compare it against the 1800 mm maximum material width. If your widest roll sits below that figure, the KT-PUR-1800 envelope is workable; the 2000 mm roller surface gives additional coverage beyond the material width.
2. Define the adhesive and the coat-weight window. Confirm that your target coating weight sits inside the published 25 to 110 g/m² range of the single gluing roller, and that PUR or hot melt adhesive is the intended chemistry for the layers you are bonding.
3. Check the heat source and the power budget. The machine is specified with electricity and thermal oil heating, a 200 kg glue melter and an oil heater, at 60 kW installed capacity. Verify that your plant can supply the required utilities and that the melter capacity fits your shift pattern.
4. Plan material handling and floor layout. Four sets of trolley with air shaft are included; unwind and rewind positions, operator access and the machine roller surface of 2000 mm should be laid out before delivery rather than after.
5. Lock the component and customization requirements. The published component set is a Siemens motor (made in China), an Inovance inverter and Schneider electric components. Kuntai provides OEM production services and customization for voltage, logo, color and machine structure, so plant-specific electrical standards can be specified at the order stage. Minimum order quantity is 1 unit, monthly production capacity is 55 units, and standard delivery time is 30-60 days.
6. Settle commercial terms and the acceptance test. Delivery terms offered are EXW, FOB, CIF and DDU, with payment terms of 30% T/T deposit and 70% T/T balance before shipment. Quality control is 100% test, and the acceptance inspection includes a pre-shipment test, which is the point at which the agreed configuration should be verified against the technical agreement.

Use Cases: Where the KT-PUR-1800 Fits - and Where It Does Not

Safety Shoe Manufacturing

Safety shoes manufacturing is the applicable industry stated for the KT-PUR-1800. In practice, the machine is relevant to the bonding steps where a coated adhesive layer has to be applied across a flexible web at a controlled weight - typically where upper materials, linings, films and reinforcement layers have to be joined before the shoe is assembled further down the line.

Foam, Padding and Reinforcement Layers

The 25 to 110 g/m² coating window accommodates both light and heavier adhesive application, which is what allows the same platform to serve lining-to-foam bonding and reinforcement-layer bonding on one machine rather than two. Where a factory runs several shoe constructions on one line, this flexibility in coat weight is usually more valuable than a higher maximum speed.

Adjacent Footwear and Flexible-Material Production

The wider KT-PUR hot melt glue laminating machine family lists healthcare, car trim, garment, upholstery, footwear, construction and home textile among its applicable industries, which indicates the breadth of flexible-material bonding the platform is built for. Kuntai's published record for the KT-PUR platform includes textile mills in Turkey, Malaysia, India and Egypt, with 120 units in Turkey and 140 units in India reported in operation over five years, described as stable operation with low maintenance. That installed base relates to textile fabric composite production rather than safety shoe assembly, and should be read as evidence of platform durability rather than a shoe-industry reference.

Where Another Machine Family Fits Better

• KT-PB flatbed laminating machine: maximum material width 1600 mm, roller surface 1800 mm, speed 0-25 m/min, electric heating, maximum heating temperature 230 degrees, 3 m heating zone and 1.5 m cooling zone, 230 kW installed.
• KT-FT-XC lamination machine for textile: maximum material width 1600-3200 mm, roller surface 1800-3400 mm, speed 0-35 m/min, electricity and thermal oil heating, PUR glue drum melter included.
• KT-HY flame laminating machine: material width 1600-3000 mm, flame burner width 1900-3300 mm, maximum speed 25 m/min, natural gas or liquefied gas - relevant where flame bonding rather than adhesive coating is the required process.
• KT-HY-H double belt press laminator: maximum material width 1600 mm, roller surface 1800 mm, speed 0-25 m/min, maximum heating temperature 250 degrees, 3 m heating zone and 1.5 m cooling zone, 265 kW installed.

FAQ: KT-PUR-1800 for Safety Shoe Manufacturing

Conclusion: Deciding Whether the KT-PUR-1800 Belongs on Your Line

The KT-PUR-1800 is a hot melt coating laminating machine with a 1800 mm maximum material width, a 2000 mm roller surface and a 25 to 110 g/m² coating range on a single gluing roller, and safety shoes manufacturing is one of the industries Kuntai lists for it. The decision rule for a safety shoe producer is straightforward: if your widest substrate fits inside 1800 mm, your target coating weight falls inside 25 to 110 g/m², and your plant can support a 60 kW machine with electricity and thermal oil heating plus a 200 kg melter, then the platform is a realistic candidate for evaluation. If your widest material sits below 1600 mm and you need a flatbed heating and cooling cycle, the KT-PB platform is the closer match. If flame bonding is the required process, the KT-HY family is the relevant starting point.
