On August 16, 2021, Sywen Packaging received an inquiry from the United States about the automatic viscous liquid filling machine, the content is as follows:

We are a professional car coolant leak repair oil manufacturer. Now we are finding an automatic liquid filling machine for filling the coolant leak repair agent with bottles and plastic cans, which economical and high-performance viscosity filling machine can meet my packaging requirements?

Our reply on August 17, 2021:

Please send us detailed information about the characteristics of the coolant repair fluid, such as its viscosity, whether it will foam during filling, and the main ingredients, so that we can recommend the most suitable liquid packaging machine to you.

The customer’s email on August 19, 2021:

The car antifreeze leak repair agent contains some ceramic microfibers and metal particles. It is a kind of liquid with a certain viscosity but good fluidity. The viscosity and fluidity of our antifreeze leak repair oil is similar to that of K-SEAL, when filling, it is not easy to foam.

Our reply on August 20, 2021:

What is the filling range in milliliters? Please send us the type and size of the liquid filling container.

The customer’s email on August 21, 2021:

The filling specifications are similar to the packaging container of K-SEAL. There are three filling specifications, 9.5 ounces, 1 pound, and 1.40 pounds, with round bottles and plastic barrels. Following is the dimensions of packaging containers of different volume:

9.5 ounces-7.5 x 6.5 inches
1 pounds-2.8 x 2.8 x 8.5 inches
1.40 pounds-‎1.8 x 3.4 x 8.5 inches

K-SEAL Coolant Leak Repair Oil Specification

Our reply on August 21, 2021:

There are three filling specifications, do you want to use one liquid filling machine or just fill one of them with an automatic liquid filling machine?

The customer’s email on August 24, 2021:

The ingredients are exactly the same for the three specifications, only differ in capacity. In order to save costs, we hope to find an economic but high-performance automatic liquid filling machine that can fill three different specifications.

Our reply on August 25, 2021:

Which filling specification has bigger packaging demands? What is the required filling speed and accuracy?

The customer’s email on August 27, 2021:

The packaging demand for 1 pound of car coolant leak repair liquid is relatively large. For one pound bottle, the filling speed is about 15 bottles /minute, and the filling accuracy error is 1%.

Our reply on August 28, 2021:

We have two models of fully automatic viscous liquid filling machines that can be used to fill your products. One is the mobile tracking type filling heads automatic liquid filling machine, which is characterized by slightly more expensive prices, more advanced technology.

Tracking filling heads follow the bottle mouth when filling, saving much filling time, and the number of filling heads is relatively small. The other one is the traditional fixed multi-filling heads automatic viscous liquid filling machine, which is characterized by a relatively large number of filling heads and a relatively cheaper price.

The price difference between the two models of automatic liquid packaging machines is several thousand dollars. Which one is more suitable for your products?

Mobile Tracking Filling Heads Automatic Liquid Filling Machine
Fixed Filling Heads Piston Liquid Filling Machine

The customer’s email on September 1, 2021:

We prefer more economical automatic viscous liquid filling machine, please quote the best FOB price.

Our reply on September 2, 2021:

Is the leak repair oil easy to have precipitation?

The customer’s email on on September 3, 2021:

Yes, it is easy to produce precipitation. When using the oil, you must shake the bottle for a few seconds.

Our reply on September 4, 2021:

Because there are ceramic and metal particles in the air antifreeze leak repair oil, we recommend to you the SY-N piston-type automatic liquid filling machine with 6 filling heads, the filling range is 100-1000ML. Filling 1BL of viscous liquid, the filling speed can reach 18 bottles/min.

Plastic oil bottles of different diameters, shapes, and widths can be filled automatically with the same one liquid filling machine. When filling, the height of the filling head diving to the inside of the bottle can also be adjusted.

Because the liquid is prone to produce precipitation, the stirrer should be added to the hopper of the liquid filling machine. Please see the detailed quotation in the attachment, the delivery time is 20 days.

The customer’s email on September 8, 2021:

The material of the liquid filling machine is all 304 stainless steel, but I need the machine to have a better anti-corrosion function, where can be made as anti-corrosive parts?

Our reply on September 9, 2021:

If there are higher requirements for the anti-corrosion of the machine, all the places in contact with the material must be made as anti-corrosion, for example, the metering piston-cylinder should be made of 316L stainless steel, and the sealing parts of the piston cylinder and the filling pipes should be made of special anti-corrosion, the filling head must be made of 316L.

The customer’s email on September 14, 2021:

How to avoid and reduce dripping when filling?

Our reply on September 15, 2021:

First of all, the filling machine can be equipped with drip-proof filling heads. Although the dripping phenomenon after filling cannot be completely avoided, the degree of dripping can be highly reduced.

Secondly, after the filling is completed, in order to prevent the residual liquid of the filling head from dripping on the conveyor belt or the bottle mouth, an anti-drip plate can be installed under the filling head. When filling, the plate will be automatically closed. When the filling is complete, it will be automatically put down.

Anti-drip Plate

The customer’s email on September 23, 2021:

In addition to filling equipment, what other supporting equipment do you have?

Our reply on September 24, 2021:

We can customize a full set of viscous liquid packaging production lines for you, including the semi-automatic bottle turntable, automatic viscosity liquid filling machine, automatic caps sorting machine, automatic bottle capping machine, automatic single or double sides labeling machine, aluminum foil film sealing machine, automatic inkjet coding machine, automatic cartoning machine, and palletizing equipment.

In addition to the filling machine, do you need other packaging equipment?

The customer’s email on September 24, 2021:

We only need coolant leak repair oil filling equipment, other machines are not needed this time. Please make a new quotation, the liquid filling machine should be made anti-corrosive.

Our reply on September 25, 2021:

OK. Please see the quotation in the attachment, it lists which special accessories will be made of anti-corrosion materials.

The customer’s email on September 29, 2021:

If purchase an automatic viscous liquid filling machine. Is it necessary to send bottle samples?

Our reply on September 30, 2021:

As long as we fully understand the physical and chemical properties of the liquid and the specific filling requirements, such as the viscosity, whether there are particles, the pH value, the size of the packaging container, and other information, it is not necessary to send liquid samples and container samples.

After more than three weeks of consideration, the customer was satisfied with the effectiveness of our communication, professionalism, and the cost of the machine, we finally received the full payment of the customer’s order on October 26, 2021. The machine was completed on Nov.17th,2021.

Before delivery, the machine had been tested for three days, the daily running time was not less than 8 hours, and we had a remote video for the machine inspection with the customer before packing. The machine will be transported to the port of Qingdao, China on November 24, 2021, then waiting to be sent to the port of destination.

The pH value of the antifreeze leak repair oil of different components is different. If the pH value of the liquid is acidic, it will be corrosive to stainless steel. If the maintenance and cleaning of the machine are not done well, the place will rush no matter the dripping liquid or the place where the filling liquid flows through it will pollute the liquid or affect the filling accuracy.

So the standard 304 stainless steel can only achieve general anti-corrosion, and cannot meet the special anti-corrosion requirements of corrosive liquids, the filling machine must be made of all 316L stainless steel material or part of 316L stainless steel material.

When consulting the liquid filling machine, please do not conceal whether your product has over-acid or over-alkaline ingredients. If the equipment is corroded and damaged due to inaccurate customer information provided, our company will not be responsible. Please provide all information accurately, so that we can provide accurate packaging solutions.
