Frequent Questions
1 . Why silicone mold appear less turning model ?
In the process of making molds adding too much silicone oil,
silicone oil destroys the molecular weight silicone , so the mold will be fewer
non-durable turning model such phenomena . If molding more complex patterns
products come with a large hardness silicone mold , there will be fewer turning
model of the phenomenon , because silicone excellent time will be very brittle
, easily broken . Conversely , if you do build a product to do with a small
hardness silicone mold , the result would be equally unsatisfactory . Because
the silicone is too soft, it will reduce the tensile and tear strength , made
out of the mold will be deformed , so turning model number will be reduced.
Plastic mold itself is very good quality , silicone no good or bad , only
suitable or unsuitable . We should adopt appropriate size product hardness
silicone to make a mold.
2 Why silicone mold have
burning phenomenon ?
Because unsaturated resin and resin product added peroxide
curing agent after the reaction in case of resin will produce a lot of heat,
general resin curing time of 3 minutes, three minutes after going to release
soon , will prevent the silicone mold burning problem
3 Why silicone mold will appear in the table dry quit phenomenon
?
Silicone mold belongs condensation silicone , which is absorbed
by the moisture in the air and cured silicone in the process of making , the
water evaporated , while there is no transferred amount of water, this
phenomenon occurs . Solution: This phenomenon does not belong to product
quality issues , but because there is no control of moisture , silica gel to
enhance shelf life , shelf life of these phenomena appear long , long time
using silica gel , add amount of 0.05% water ,
the problem can be solved.
4 Why silicone mold appear poor tension phenomenon ?
Because the client in the production process of the mold in
order to reduce the viscosity of silicone , silicone easy to make large amounts
of silica in a silicone oil is added , this will become very soft silicone that
produce intolerance pulling the tear strength is reduced , Rally deterioration
phenomenon resulting mold is not durable , life is short, less turning and so
on.
5 Why mold will appear oil flush?
Silicone mold itself have no oil flush problem , just because
during operation adds composite silicone ( silicone oil with white mineral oil
complex ligand ) as white mineral oils are petrochemical products, not silicone
.
6 Why mold have aging phenomenon ?
In the process of making silicone molds , we recommend our
customers the best without any oil, if necessary , the amount of silicone oil
added up to no more than 5 % to 10 %. Because the addition of silicone oil will
destroy the molecular weight silicone too , so do not come out of the mold will
produce acid , intolerant aging phenomenon.
7. Why silicone mold have surface marks , stripes, not smooth
and so on ?
This phenomenon is a product or a model to be replicated no
grinding or polishing sake. Because in fact the model or the product itself is
not enough to smooth or perfect , so the product or model to be copied if not
polished or polished , even the best silicone molds will do pretty, is not
smooth enough . Another case is , when playing a release agent , no uniform
brushing can also cause mold surface problem.
8 you know the usage of
mold silicone?
Silicone mold is mainly used for toy and gift industry , craft
industry , furniture decoration industry , figures copied , building decoration
industry , resin handicraft industry , unsaturated resin crafts industry ,
candle craft, Plastic toy industry ,Gifts stationery industry,Gypsum gifts
industry, mold manufacturing industry, Bolero industrial , simulation plant and
animal sculptures, Buddhist carvings crafts products and other industries copy
and mold making .
Mainly in used in toys , gifts, floral fine products for packet
mode , filling mold products , glass , lighting , candles , figures copy
production molds , large products , open- slice mode , relief , statues , gifts
making molds , sole model , perfusion mold, sand- casting.
A variety of different uses specific operations silicone mold is
also not the same , what is required to achieve the specific operation must be
based on a variety of different parameters.
How to clean
General production mold clean up our way is the use of
sandblasting ,place the silicone products mold into blasting machine, blasting
head is aligned with the production of silicone products mold cavity , and then
gradually Sort cavity by sandblasting .
