Principle of Production
Typically,the production line is to produce 3 layers(ABA)hollow
construction formwork. Adopting three layer distributor and
co-extrusion technology, the material pp(or recycled pp) and other
additives go through a complete production in which all these
materials heated,mixed,sheared,and co-extrudered in single screw
extruders to finally form the three layer pp hollow formwork sheet
in the T-die mould whose thickness can be adjusted,then the
extruded 3 layer sheet is hauled forward to a calibration station
where it is cooled andvacuum calibrattheed for certain shape,and
finally cut and stacked.

Engineering Drawing and Equipment List
PP Hollow Formwork Advantage
1.Light in weight, high strength,high hardness, impact resistant,
tear resistant.
2.Surface is smooth,bright and clean,then to make the concrete
block surface smooth.
3.Good concrete forming.
4.Moisture absorption,no deformation,mildew resistant,steady in
size,especially suitable for underground and damp environment.
5.Acid and alkali resistant, corrosion resistant, preservative
treatment is not required both during use and storage of
formwork,and will not make any pollution.
6.The reusable time for pp hollow sheet can reach more than 50
times,long service time.
7.Eco-friendly,can be recycled to granulate to feed as raw
material.

Aftersales Service
1.Technical documents
All the symbols on the equipments should be in English. Seller is
responsible to provide general layout plan, electric plan,
installation direction, and manual book in English to Buyer on
time.
2. Arrangement for inspection, installation and testing work
a. After all machines are delivered to customer's factory; Buyer is
responsible for all preparation work, e.g. electricity supply,
water supply, labors and cranes, etc.
b. ACEMIEN will prepare for visa application for their engineers,
who are responsible for guide of machine installation and testing
at the Buyer's factory.
c. The Buyer will buy the round-trip air ticket for Engineer if
visa application is approved. The buyer is also responsible to bear
expenses generated, e.g. visa formalities, meals, accommodation and
allowance of USD100 per day for each engineer.
d. Engineer will give free training lessons to labors in buyer's
factory.
e. If buyer doesn't request installation and commissioning by
Seller's engineer in 4 months since date of bill of lading, which
to be accounted all the machines has been successfully tested by
buyer.
3. Quantity and quality guarantee
a. Quantity/Quality Discrepancy to destination port during transportation:
In case of quality/quantity discrepancy to destination port in
transportation, customer should file claim within 30 days after the
arrival of the goods at port of destination. Insurance company and
shipping company will be responsible for any discrepancy of the
