Cast Iron Rotomolding Plastics
Polyethylene is commonly used to produce rotational molding products and this kind of material has its own characteristics.
Polyethylene is a kind of macromolecular compound that formed by addition polymerization of ethylene, and based on polymerization conditions, the number of molecule may varies from one to several million. Polyethylene is white and semi-transparent, little flexible, non-toxic and flammable. When melting, it smells like paraffin. The performance of polyethylene is related to its molecular as well as the degree of crystallization.
1. The plastic can be easily and cheaply made into powder or paste to ensure a faster heat transfer between raw materials during the process of rotational molding
2. The melt flow rate (MFR, also known as melt index) of the plastic should be appropriate, that is means that the raw material must have good fluidity (flowing by itself and hanging the wall in the mold cavity) in the case of no external force after heating and melting.
1. Can you provide sample?
Yes, please feel free to tell us, also your own design is welcome to make sample for you, After confirming the authenticity of your company, we are willing to provide small quantities of free samples.
2. What types of rotomolding machines do you manufacture?
It is fast and easy to start once you can send your product drawing or picture with size or sample to us! What is more, we will do more works to help you get the perfect product, such as:
a.Product material, structure, application,thickness ,inserts;
b.Mould material, locking system, hoist safety,machine placement, demoulding effciency;
c.Sample tes. All above is respect to customer' s initial design or work under confirmed modifcation, a professional manager to follow up from start to final accept.
