Paper pipe variable diameter tee

Baoji Huaguang Casting Material Science and Technology Co.,Ltd

 is a specialized corporation for new types of casting materials, we have been committing to the development and production of ceramic sprue tube for casting, papery sprue tube for casting and the exothermic insulation riser head,We have got 25 patents.We joined the Casting Association of China, we are privately operated corporation and we are the Advanced Corporation in Property Rights of Baoji City.

Papery sprue tube for casting is our newly developed product which is green energy-saving and environmental-friendly,It is an ideal substitution of ceramic sprue tube for casting.Our research & development group and the specialists of Xi`an Jiaotong University spent many years on the Papery sprue tube.It mainly used for Lost Foam Casting, EPC(expendable pattern casting), traditional sand mold casting, the coated sand casting and other casting methods.

It has positive effect on improving the quality of casting products, reducing waste, increasing the quality of reclaimed sand and reducing the operating strength.Papery sprue tube for casting is firstly created by us and it`s a revolution in sprue tube for casting.

Main advantages

1.Light and easily operated

The weight of Papery sprue tube for casting is only one tenth of the ceramic sprue tube in the same size, you can operate it easily, reducing 70% of the labor.

2.Easy cutting and without pollution

Papery sprue tube can be cut by papery knife, with less cutting dust, so it can improve working environment and working strength.

3.Reduce the risk of sand with best seaThe joint of Papery sprue tube applies socket and spigot joint,so there is few chance for malposition, the rigor joint won`t let sand in, so it can reduce the chance of sand-mixed product.

4.It won`t work with liquid metal.Papery sprue tube won`t burst or adhere when pour, it is slag-resistance and anti-erosion.

5.High strength and lasting, resist decay  .The Compressive Strength of Papery sprue tube is 18 Mpa in normal temperature, after several experiments, in won`t damage when fall from 1.5 meters high.

6. No recarburization& carburization.The papery sprue tube can ensure a steady character of casting foundry.

7.Increase the quality of reclaimed sand and reduce abrasion of equipment.After pouring, the papery sprue tube go carbonizing, leave little  waste, the amount is about one twentieth of the ceramic sprue tube, it`s also easy to peel off,  so it avoid the pollution from sprue tube to the casting sand, it also solve the problem of sand-recycle-abrasion from ceramic sprue tube as well as the blocking of sieve.     

8.Energy-saving and Environmental-friendly.The papery sprue tube is made from waste paper and other organic fiber and fireproofing material.It won`t produce pollution when using, it is a typical green energy-saving and environmental-friendly product.

9.This product has been used by a casting company in China, it has been confirmed that all the performance meet high standard.
