What Our Customers Have to Say
We received the machine on time. With the help of The After-sales team of COWIN, it has been installed and debugged and put into production, The performance and output of the machine are up to our requirements. Cross-border trade is not easy, but this cooperation has strengthened our interest to cooperate with Chinese manufacturers in the future. Despite the difficulties of the project, Cowin has a good attitude.
The machine is the same as I excepted. The quality of your product is very competitive on the market. We have cooperated with other Chinese manufacturers before, Your goods are superior in quailty compared with those of other manufacturers. One thing we are not satisfied with that The delivery of cabinet is a bit slow, But the buyers have been helping us track the flow of goods in real time, thank you for your guys efforts.
Single Screw Extruder
In the field of degradable materials, we are still new, but we are very interested in degradable materials, which is a global trend. COWIN friends provided us with the best services and solutions. Even if we had many questions and doubts, COWIN friends answered them one by one. Finally, we cooperated. Thank you very much for this cooperation. This is our first production of degradable materials. I believe we will have more cooperation with you for degradable materials in the future.
Your machine is great and the service is nice. Every time we cooperate with you, we are happy. Even under the influence of COVID, when we urgently need parts, our production is not affected, because you have provided us with sufficient spare parts inventory and delivered goods quickly. We are very grateful. For us, time is money.
Extensive Experience in Applications
The color masterbatch is composed of three basic elements: pigment or dye, carrier and additive. It is an aggregate made by super-constant pigment uniformly attached to the resin, which can be called pigment concentration.
Compared with general plastics, engineering plastics can meet higher requirements in mechanical properties, durability, corrosion resistance, heat resistance and other aspects, and it is more convenient to process and can replace metal materials.
Filling masterbatch can be used to process plastic films, garbage bags, shopping bags, vest bags, packaging bags, etc. It has good dispersibility, blown film has no white spots and black spots, high fineness to guarantees product gloss and toughness.
Non-crystallization dry pet sheet extrusion has following advantage: Use in producing PET / PLA sheets , no need pre-drying crystallization of the energy consumption and adapt to the material for the production of the second , high yield , low energy consumption, high quality plastics characteristics.
