HEWEI Applying the technology of Polyurethane 2.0
To the production of furniture products

The polyuerthane (PU) material is environmental friendly,which was first innovated by Otto Bayer in German in 1937.
The innovation of this new material led to a new industrial revolution. It was widely used for interior accessories of cars because of its durable and environmental friendly properties.

The polyurethane (PU) material is durable and environmental friendly, and its lifespan is longer than 6 years.
But it could only be used for interior accessories of cars because of the high cost of technology
and loss in those years. It is obvious that the technology needs a secondary development
and improvement so that this good material can be used for civilian products.

----------------------------------------------------------------------------------------

In 2003, HEWEI made decision to develop and improve the technology of Polyurethane (PU) 2.0
10 years later, this technology can already be used for commercial and civilian products.

“Technology, should make contributions to the cause of environmental protection”
Adhering to this conviction, HEWEI Technology develops different product lines
by making full use of the non-toxic, environmental friendly, fire-retardant, and
long-life properties of polyurethane.

Commercial Seat Products: Commercial Row-Chairs
For public areas like airports, hospitals, cinemas, etc.
( fire-retardant, anti-bacterial, and long-lifespan).

Civil Seat Products: Office Chair, Dining Chair, Bar Chair
Products with new designs for civilian usage are put into markets, which have a
lifespan up to 6 years, do not peel, not produce peculiar smells, and give people
comfortable body feelings since their surfaces are close to normal temperature,
warm in winter and cool in summer.

Manufacturing Process Introduction

图片关键词 图片关键词

Molds are custom-made to orders
and developed by batches.

Molds are custom-made to the requirements of
customers.
Molds are made by aerospace steels.


※ The picture shows the process of in-mold coating
and getting ready for foaming.


The iron seat frame is closely linked with the Polyurethane (PU) like fresh and blood after foaming.

The iron frame is built-in, and has a 2-4mm thick skin layer after foaming.
So the lifespan of the product is prolonged to more than 6 years.


※ The sponge cushion is integrated with the iron frame, and thus the seat is soft and durable.

The foaming temperature is precisely controlled within a certain range.

The integral foaming is even and full.
The leather surface is smooth and textured.
The rate of finished products is high.
