MIXER

The start of production starts with mixing the products in the Mixer. The main raw material is PP (polypropylene) with a small amount of Masterbatch and other polymers added.

Mixer
Sigimi	100kg
Motor speed	4kw
Rotation speed	300
Weight	700kg
Voltage	380v
Dimensions	1700*1400*2900

EXTRUDER LINE

It is one of the most important parts in extruder production. The production capacity of the extruder is selected depending on the number of weaving equipment you will receive. Extruder is considered part of making yarn for bag weaving from granule. Depending on the type of bag, its thickness and width can be changed.

The equipment produces tapes (threads) by heating polypropylene and high-density polyethylene. These threads then go to the winding equipment. The equipment can use 100% recycled PP(polypropylene) and PE(polyethylene), powder or granule form PP and high density PE as raw materials. Extruder screw and cylinder are made of 38CrMoA1A alloy steel. If the equipment is treated with nitrogen, its strength will increase even more. Equipment rollers are coated with hard Cr(chromium) material.

THREAD WINDING PART

In this part, the finished threads are wound on special spools. The wrapping process is controlled by a computerized system. This part is also selected depending on the number of pieces of weaving equipment.

This equipment is equipped with a 2.2/3 kw motor to increase energy efficiency using the latest technologies. The parts in the equipment are easily replaced, due to which the spare parts wear less, move more stably and roll flat.

Main engine power	2,2kw
Winding motor power	9kw
Installation dimensions	6200*1620*1600mm
Weight	3400kg

BAG WEAVING EQUIPMENT

Weaving equipment will vary depending on the diameter and density of the product you are producing. Our widely used bag weaving machines are 4G and 6G models. If you intend to produce bags intended for Big bag, i.e. 1 ton products, then 10G-12G models are suitable for you. To change the diameter of the bags, you need to add molds for a special cylinder.

If we compare with old models, this equipment has more and better facilities. For example, the principle of operation of the equipment is simple and stable, no special oil is needed, it emits less than 82 dB (decibels).

 

WEAVING EQUIPMENT
Rotation speed	140-180ps/min
Hardware power	4,5kw
Sigimi	65-120metr/h
Main engine power	2kw
Dimensions	8500*2200*2650mm
Weight	2000kg

BAG CUTTING, SEWING AND 4 COLOR PRINTER EQUIPMENT

This equipment outperformed previous models and production processes, significantly speeding up the bag production rate. Cutting and lining the bags by hand is a labor-intensive and labor-intensive process. Therefore, it is advisable to entrust this part to automatic equipment.

Equipment features

1) Due to the fully automated equipment, one worker can manage all processes in the equipment.

2) The whole equipment is made of Q235 iron, so it works faster and more stable.

3) It is possible to install a hot cutter and a cold cutter in one piece of equipment. It is enough to press one button to change the cutting blades.

4) There is less damage to the environment due to the smoke absorption function.

5) Inks are automatically poured into the printer.

6) There is a two-layer drying system. This will help the bags dry faster.
