Sino package thin wall cap mould
Now in Sino Mould factory, there are four thin wall cap moulds. Its difficulty lies in the following points
1. The wall thickness is very thin. Therefore, it is easy for out shape, gas bubbles and flash.
2. We added air valves in the cavity and core. Otherwise, it will stick to the cavity and will be out of shape when ejection.
3. The gate diamenter should be ajusted by the cap size
Now Sino mould has special mould design of ths kind of cap, we have the ability to modify those above points
1. We will increase hardness of the fixed plate of cavity.
2. make excellent cooling of core and cavity. Add another water channel for the fixed plate of cavity.
3. For the demoulding, we use four ejector pins and eject parts.
If you are interested in our packaging mould, please feel free to contact me.

Buying a plastic injection moulding machine is not a small investment.
Too much machine for the job at hand is wasteful; too little machine does not get the job done.
Careful matching of the job's needs and the factor of a plastic injection moulding machine is well worth the effort.A good plastic injection moulding machine produces consistent parts from shot to shot, and does so in reruns of the same job.
Choosing a plastic injection moulding machine simply on the basis of shot weight is too simplistic.
The following is the three main factor to choose plastic injection moulding machine.
1. Shot weight:
Shot weight is an important factor of the injection unit of a plastic injection moulding machine.
Expressed in ounces or grams, this is by far the most commonly used single factor to choose a plastic injection moulding machine.
Once the plastic material is selected, it has a weight. A plastic injection moulding machine with sufficient shot weight is then chosed.
Some manufacturers prefer to use injection volume as the starting point to state the shot weight of their machines, instead of using measured shot weight.
2. Choosing a machine which is not too big:
A plastic injection moulding machine of a specified shot weight can be used to mould article including the runners weighing from 35% to 85% of the shot weight.
If a big machine is used to mould small articles, the melt in the barrel could degrade due to unduly long residence time.
Moulding small parts with a big machine is inefficient in energy usage per kg of material processed, also known as specific power consumption.
Having multicavities per mould to increase the articles' weight and to increase the mould size are solutions to using bigger machines.
Alternatively, lowering the barrel temperature would help avoid degradation due to long residence time.
3. Clamping force:
Clamping force is an important factor of the clamping unit of a plastic injection moulding machine.
It is the maximum force the machine is capable of to keep the mould closed against the cavity pressure during injection.
Insufficient clamping force gives rise to flash at the mould joint. Most plastic injection moulding machines today use their clamping force (in tonnes) in their model name,
It is advisable to use a sufficient clamping force below the maximum. The sufficient clamping force is proportional to the projected area of the cavity.
Projected cavity area is the cavity area projected onto the plane at the mould parting surface.

The injection machine can be divided into vertical injection machine andhorizontal injection machine.
The vertical injection machine and horizontal injection machine have their own features. The feature of vertical injection machine as follow:
1. It can easily take out the plastic parts from cavity by a simple robot, in favor of precision molding.
2. The clamping system is open, easy to match various automatic devices, adapt to automatic molding of complex and precision products.
3. Easy to ensure the uniformity of mold resin flow and mold temperature distribution.
4.. When small batch production, the mold structure is simple, the cost is low, and easy to uninstall.
5. Stand the test of several earthquakes, due to the center of gravity of vertical injection machine is low, so the anti-seismic is better than horizontal injection machine.
The feature of horizontal injection machine as follow:
1. Even for large-scale injection molding machine, due to the body of the injection machine is low, there is no any height limit for the placement of plant.
2. Products can automatic demould, without using the robot also can automatic molding.
3. Due to the low body of injection molding machine, it's easy to feed material and maintain.
4. Mold can be installed by crane.
5. Multiple injection machines arrange in a line, the molded products are easy collect and pack by conveyor belt.

An Injection molding machine is a machine for manufacturing plastic products by the injection molding process.
Injection moulding machine is the main molding equipment which can make thermoplastic or thermosetting plastic into various plastic products by using plastic moulds. It can be divided into vertical, horizontal and all-electric models. A typical injection moulding machine consists of the following major components.
The injection system, the mould system, the hydraulic system, the control system, the clamping system and typical molded system.
Injection molding machines can fasten the moulds in either a horizontal or vertical position. The majority of machines are horizontally oriented, but vertical machines are used in some applications such as insert molding, allowing the machine to take advantage of gravity.
There are many ways to fasten the tools to the platens, the most common being manual clamps; however hydraulic clamps and magnetic clamps are also used. The magnetic and hydraulic clamps are used where fast tool changes are required.

China PVC injection molding service, Sino Molding is China PVC injection molding service supplier, offer high quality China PVC injection molding service.
Sino Molding is famous China PVC injection molding service company, we supply many kinds of injection molding service.
PVC is thermal sensitivity material, the injection molding machine technology is not very well. The reason is too high melting temperature or too long heat time easily decompose the PVC, so control melting temperature is the key of injection molding PVC products.
The heat source of melting the PVC material is come from two aspects, one is made by screw movement, the other is resistance wire of barrel outer wall. Because the thermal conductivity of PVC is poor, so in the heating process, the outer materials have been heated, but the inner materials also in condensation condition.
Even the outer materials have decomposed, the inner materials maybe haven’t melted. So for all these reasons, we should pay full attention on the product design, mold design and injection molding technology, especially select and use PVC special injection molding machine of excellent manufacturer to manufacture perfect products.

PVC injection molding machine is special designed for PVC raw material injection,the barrel and screw use stainless steel material,with cooling fan outside of the barrel.The flame for PVC machine is bigger than common injection molding machines in order to fit the PVC pipe fitting mould sliding structure.
PVC raw material is a kind of easy degraded plastic under high temperature,so the plasticizing temperature should not be more than 180centi degree.We put the cooling fan outside the barrel in order to avoid the inner temperature too high.PVC plastic raw material is also corrosive to steel material,that's why we use special steelness steel material for the barrel and screw which touch with the melting material directly.
With plastic injection mould and molding machine manufacturing workshop,Sino Mould could offer you one stop service for the injection molding line,include PVC fitting molding line,PET preform molding line,IML molding line,crate molding line,Chair molding line,pallet molding line,dust bin molding line and so on.We could supply technology training if you are new in the injection molding industry.Welcome your enquiry.
