Plastic Container Thermoforming

//polytype OMV Extruders are supplied in a range Ø 45 ÷ 170 mm. They come in four basic models, identified by the rolls diameter: 750, 500, 350, 250 mm. The original, thoroughly tested OMV extruders’screw design for various materials (PP-PS-PET-ABS-Multilayer) is constantly upgraded to fit raw materials’ improvements, so as to achieve optimum quality and throughput.

The combination of both in-house testing and feedback of “in-service” machines has allowed //polytype OMV to develop extruders that both maximise machine efficiency and suit customer requirements.

Today’s extruder is the result of thirty years’ technology and know-how; constant research coupled with rigorous testing programs has made //polytype OMV a world leader in the manufacture of precision extruders for mass production of high quality plastic sheet.

WORLD RECORD IN THERMOFORMING

//polytype OMV international patent „revolving mould“ forming technology for highest production and best precision

Forming area: 770 x 480 mm

RM77 “REVOLVER” features a unique, patented “Rotating Mould System” for thermoforming, which allows much longer cooling process at very high speed, especially studied for materials like polyolefins that need longer cooling period. Its forming station and automatic product handling are designed for multiple row moulds, in-line and/or staggered layout.

RM77 is the first machine to break the barrier of 50 cycles per minute with PP cups, a major step forward in thermoforming technology. At its debut in 2016 the machine reached a world-record 174,000 cups per hour, producing Ø71 mm PP drinking cups

F88 - Precision in every situation

The large platen universal thermoformer for shallow products

Forming area: 1280 x 750 mm

F88 is an automatic large-size thermoformer whose special feature is its modular configuration. Available in two different versions:

• Single-Station/In-Mould-Trimming (punch-and-die moulds), to produce plates, trays and lids in PS, PP, PLA and other biodegradable materials
• Multi-Station/Separate Trimming (steel-rule cutting moulds or punch-and die moulds), to produce trays, baskets, plates, boxes etc. in PET, PS, PLA and other biodegradable materials

F87 – Think big

The ultimate large universal thermoformer

Forming area: 850 x 650 mm

F87 is a fully automatic, electro mechanical driven, thermoforming machine with in-mouId trim, which nullifies shrinkage effects on trim accuracy. It has been designed to process all types of thermopIastic materials.

F87’s forming station and automatic product handling is designed for multiple row moulds, in-line and/or staggered layout. The international patented “vacuum plate" and unloading system, including stacking and counting, provides a labor free handling with high hygienic. The design incorporates the “Smart Drive” and the moving parts in automated product handling are made of Iight weight, durable carbon fibre material, which assures optimized cycle speed with lower production costs.

This machine features a special Rim-Rolling System by compression, an //polytype OMV international patent, that doesn't require further product heating.

F86 – Two dynamic versions

F86 is a fully automatic electro mechanically driven thermoformer with in-mould trim, which nullifies shrinkage effects on trim accuracy, it has been designed to process all types of thermoformable materials, including polypropylene, and coextruded barrier materials.

This machine is characterized by a special ejection and unloading system (an //polytype OMV international patent) including a guided vacuum plate, 4-station rotary transport wheel, a stacker, a rotary arm and one unloading robot. In addition, the unloading and transfer conveyors have been especially designed for handling shallow products with minimum stacking height and for eliminating "de-nesting" of different product types thanks to the adjustable inclination setting. There is also available space to install optional quality control station, hole-punch station or other in-line operation before stacking and unloading.

//polytype OMV "quick mould change feature" minimizes down time for mould changes. The cutting device is made by eccentrics placed on the upper press (an //polytype OMV international patent).

E76 – The wild one

//polytype OMV international patent „shuttle mould“ forming technology for higher production requirements

Forming area: 760 x 540 mm

E76 is a fully automatic, electromechanically driven, thermoforming machine with in-mould trim, which nullifies shrinkage effects on trim accuracy. Designed to process all types of thermoplastic and coextruded materials, E76 features the international OMV patent "Shuttle Mould System" which allows cooling 3.5x longer than any conventional machine, particularly suited to materials like polyolefins.

Thanks to the reduced opening stroke of the forming press, this system allows a thermoforming polypropylene cycle speed as high as the polystyrene's one. E76 also features a special Rim-Rolling System by compression, an OMV international patent, that doesn't require further product heating. In addition, it also lets unloading and stacking products of different heights.

F37 – The smart driver

The medium large universal thermoformer

Forming area: 780 x 420 mm

F37 is a fully automatic, electro mechanically driven, thermoforming machine with in-mould trim, which nullifies shrinkage effects on trim accuracy. Designed to process all types of thermoplastic materials, F37’s forming station and automatic product handling is suitable to multiple row moulds, in-line and/or staggered layout. The international patented "vacuum plate" and unloading system, including stacking and counting, provides automatic and highly hygienic product handling.

F37 features the Smart Drive; moving parts in the automated product handling are made of lightweight, durable carbon composite material, ensuring optimized cycle speed with lower production costs.

This machine incorporates a special Rim-Rolling System by compression, an OMV international patent, that doesn't require further product heating.
