Why S.S Metal Sand is the best choice for fiber spinning

1 ) Extension Component life, greatly reducing the production cost. Metal sand filter material will be more than 3 times long life than the glass beads,common sand and other filter materials.Because of its high profiled metal sand, large surface area, strong ability filter impurities to extending the life of components. Reduces the component related accessories(filters, washers, etc.)cleaning cost.
2) To Reduce the spinning yarns breakage, irregular convex metal sand sharp features are unmatched by conventional filtration material, this sharp with high hardness which are not easily deformed even under pressure of 40MPA.During the filtering,can pierce the bubbles,barriers and aggregated particles to improve filtering precision.
3) Stable component pressure,slow and steady in the pressure rising,to avoid instability caused by pressure fluctuations in production,instability quality and etc.The metal sands ability will not change by the changes of pressure and temperature.
4) Improve the uniformity and the melt spinnability, stainless steel is a good conductor of heat which can guarantee melt sands temperature to fit the component compartment temperature.
5) Stability chemical ability.No adverse reactions with polyester melt.
6) Easy to use, no need cleaning& drying like glass beads, sand, emery.Because our production has been conducted in high-pressure cleaning process, the factory’s products have done in clean.

Cost Savings
If 25 days cycle life of sea sand ( usually 25-30 days ) , metal sand 40 days ( usually 45-60 days ) , fiber fineness 100D, a component assembly with an estimate of the amount of sand 200g . That is eight times using sand replacement components ( 25 days * 8 = 200 days ) , and the use of metal sand replacement five sub-assemblies ( 40 days * 5 = 200 days ) to the same production cycle time.
A component cost by using sea sand as follows: a mat 5$, cleaning costs 1$( water, electricity, gas , materials, labor, management, etc., many enterprises greater than 1$) , the component materials under the machine loss of 100 grams ( Total 0.2$ ) , the open position marker 200 grams ( count 0.4$ ) , you need to sand the cost is 0.1$, the total cost of a cycle : ( 5 +1 +1 +0.2 +0.4 ) * 8 = 60.8$; If under the same conditions , a component requires metal sand costs about 1.2$, the use of metal sand a cycle costs as: (5 +1+1 +0.2 +1.2 ) * 5 = 42$, a savings component a cycle cost 60.8-42 = 18.8$. Because the metal sand brought improvement of product quality , as well as the stability of the production process to improve the benefits and costs of production, on the use of metal sand the direct impact of cost savings is about 20.1% than other materials, the metal sand a year for one cost-saving will be 24$. Specific to different companies will vary ,some companies cyclicality can reach 90 days and will be more cost savings.

Excellent performance of metal Sand in production

1.Excellent metal sand structure.
2.The cycle of metal sand generally will be more than 40 days, the longest period can be 90 days.
3.Excellent stability for FDY, porous fine denier , cationic, PBT, PTT, nylon , and other differentiated functional fibers spinning.Such as the 75D/144F POY and etc.

Note:
A.Density Test Methods:Put 800 cm3 empty beaker on the platform, then fall into metal sand at a distance of 20 cm,stopped when the beaker filled the sand.Weight in grams and the volume of the beaker will be the metal density.
B. Above density only as a reference, the actual use of the density will be according to the specifications and requirements of the pressure component set.

Component Pressure
Should be ± 10bar after 6 hours the machine components working.

The appearance checking
Uniform size,no rusting,uniform acute angle, spherical objects = 0.5%.

How to use
1 The metal sand in the our production process has been rigorous cleaning and filtering , no need washing or filtering before using.
2. Before using , please check the specification.
3. Avoid dust and debris into the metal sand bag.
4. Several specifications layering can be used, in several specifications between each layer is best to put a stainless steel mesh filter.The closest spinneret will be higher mesh sand.
5. According to the requirements of the production process of the metal component ,you should use a copper bar to hit to increase its density , and then use a stainless steel rod ( rod length 15 centimeters,end must be smooth ) to press on the position of the metal sand surface(About 10 kg pressure,clockwise or counterclockwise rotation around the metal sand surface) to void the same positions uneven density.
6. No gap allowed.
7. If boost slow or for a long time does not boost, this is a normal phenomenon.
8.When reach maximum pressure Please timely replace the components in order to avoid producing substandard products.
9.This product is disposable after use which can not be used again.
10.Our metal sand is long life ,please track or record the time.Meanwhile,Please make the silicon nozzle plate trimmed regularly to ensure the quality and continuity.
