The
Tincoo DHB-M120/DHB-M280 series blow molding machines are developed by Tincoo for high-capacity multi-layer co-extrusion blow molding applications, suitable for producing chemical drums, large daily chemical containers, and other products. Adopting an advanced 6–7 layer co-extrusion system design, it ensures full melting of various resins and smooth flow channels with no dead zones.
Tincoo blow molding machines mainly feature a large-scale floor-standing frame and a box-type mold base design for stable structure. This series supports vertical or inclined blow molding. The newly designed blowing mechanism is equipped with an exhaust pipeline to accelerate product cooling. The machine can be optionally equipped with automatic ringers, automatic trimming systems, manipulators, and other automated units to meet high-output continuous production requirements
Product Overview
The DHB-M120/M280 models are 6 to 7 layer co-extrusion blow molding machines that enable parallel extrusion and co-blowing of multi-layer materials. The extrusion system consists of 6–7 single-screw extruders with screw diameters ranging from Φ40 to Φ100, configurable according to layer requirements and product specifications.
The machine is equipped with an ejection-type mold base where the platen moves vertically, providing a robust and easy-to-change mold installation area. It features hydraulic mold clamping, hydraulic or servo air injection systems, and a blowing mechanism with vertical or inclined blowing and exhaust pipelines for fast parison cooling and solidification.
The control system uses a PLC/touch screen interface (brand not specified on the page), with advanced functions including automatic thickness measurement and control, and inertia adjustment (details not specified on the page) for precise parameter control.
Process and Application Scenarios
The DHB-M120/M280 series is mainly targeted at applications requiring high-performance multi-layer large containers, such as:
- Chemical industry: Corrosion-resistant chemical drums, pharmaceutical containers, etc. Multi-layer structures can incorporate barrier layers to improve chemical compatibility.
- Beverage & food industry: Large-capacity beverage drums, milk drums, seasoning barrels, etc. Multi-layer structures enhance oxygen barrier properties and preservation performance.
- Daily chemical industry: Large packaging bottles for detergents, shampoos, etc. Multi-layer structures reduce costs while ensuring appearance and moisture resistance.
- Medical & hygiene: Medical containers requiring high printing quality and antibacterial properties. IM-Blow technology (injection-blow molding integration, aluminum foil integration, etc.) improves label stability.
- Special plastic products: Large-scale plastic fuel tanks, intermediate bulk containers (IBC), etc. Multi-layer barrier co-extrusion meets industry standards.
The DHB-M120/M280 can be equipped with in-mold labeling technology for one-piece forming of bottle bodies and labels. It can also be matched with a fully automatic deburring/trimming system to greatly improve production efficiency for large drum products.
Tincoo also provides fully automatic double-station parallel blow molding machines (for higher output) and robotic automatic loading/unloading systems to meet large-scale production line requirements.
Advatages
Compared with traditional single-layer blow molding machines, the multi-layer co-extrusion design of the DHB-M120/M280 offers significant advantages:
- Improved product quality: Multi-layer structure optimizes material ratio of inner and outer layers, enhancing mechanical strength and durability. The outer and inner layers can use virgin materials, while the middle layer can be recycled or barrier material to balance cost and performance.
- Process flexibility: Fast switching of materials and color layers without extra processes. Multi-layer flow channel design ensures smooth extrusion without dead zones.
- Production efficiency: Compatible with automated systems such as automatic ringers, deburring machines, and stacking manipulators, reducing manual intervention and improving automation.
- Energy saving & environmental protection: Rational energy management keeps power consumption at approximately 220 kW. A circulating water cooling system reduces power usage. The fully automatic deburring system replaces manual trimming, improving safety and enabling automatic scrap recycling.
- Intelligence: Optional PLC + touch screen control, multiple self-diagnosis and alarm functions, user-friendly HMI for easy operator training. Manual adjustment devices on mold moving parts allow precise positioning of molds and blow pins.
- Direct factory supply: As the original manufacturer, Tincoo provides customized design, fast technical support, and spare parts supply. Products are sold globally with a one-year free warranty for spare parts.
Among comparable multi-layer blow molding machines, the DHB-M120/M280 stands out with large mold compatibility, full-layer co-extrusion, and automation integration. It is ideal for ultra-large capacity, multi-cavity parallel production to boost output and product quality.
