 Previously, we basically use egg trays which made of paper, of course, we also use thermoforming plastic tray. But they have a variety of defects, the paper tray is not waterproof, and for environmental protection, we should try to avoid using paper egg tray; and for thermoforming plastic tray is not strong enough for stacking, so now more and more farms choose to use injection molding plastic egg tray.

Using plastic egg tray, both to avoid the using of paper, and strong enough for carry and stacking; you can customize a variety of strength plastic egg tray according to carriage requirement. Besides, plastic egg tray can be fast production, a small injection machine and mould can produce about 7000-8000 plastic eggs trey a day. Moreover the equipment costs for plastic egg tray is not high.

 

 
plastic egg tray equipment

double color PC cup molding line
 
In chinaplas 2014 shanghai, sino mould have exhibited our new PC double color injection molding line to show our new approach in plastic molding field. Though in previous year, sino mould already has the technology to make double color injection molds and machines, but that one is with 2 molds fixed on machine rotate plate, by machine rotate plate turns, it reaches with 2 kind of material or 2 kind of color molding.
 
This time we exhibited is with PC double color molds manufactured with rotating structure, machine with normal injection location position and side one for 2 different material injections.
 
For our PC double color cup molds, it is not only for double color molds and machines, also special for PC material molding. With pc material, on mold steel choosing, it is better to consider good mold polishing and polishing lasting, in this way, it make PC cups with high transparency. Also for PC material molding, it needs to get high temperature of 75-80 degree of mold temperature; this way would also help for PC cup with high transparency.

To one plastic injection mould, there are several systems.
Such as mould guide system, mould cooling system, mould heating system,
mould injection system and mould clamping system.
Every system have detail requirments regarding different mould structure and standard.
We just take the clamping system as example:
Usually it has requirments regarding the mould clamping device:

1 To have sufficient clamping force.
at the meantime it should be ensured that there is no overflow appear under the pressure.
2 To have sufficient injection mould plate area,stroke and space to suit for the molding of plastic parts
with different shapes and dimensions.
3 The running speed of plastic injection mould plate should be fast at first and then slow when mold clamping.
and then slow then fast during mold opening. It is way to avoid collision of moulds during mold clamping
and to have the plastic parts ejected steadily.
4 Sufficient intensity of plastic mould plate should be ensured to avoid distortion or damage to the molds
during molding as incurred by the frequent pressure applied there to,
It may has influence in the steadiness of the products dimension and service life of the injection molding

 


 

Besides, many details will also need to be considered in the mould clamping system.
As a professional plastic moulds suppliers, we walk towards better and higher efficiant moulds.
If you need any more information, please feel free to contact us.

 Sino mould famous plastic industry molds supplier.

We keen on offering high standard various type of industry molds,

such as industry helmet molds, industry junction box molds,industry building production molds and plastic traffic cone molds.

 

We supplied our customer high mentality  traffic cone molds.

In traditional way, the molds for plastic traffic cone will need bigger moving stroke machine,

that means even though the machine can meet the demands for injection weight and tie bar distance,

as usually the part is high and sharp, we will still need bigger size injection machine than before.

It will take big waste for injection machine budget and energy waste,

When designing the mould, we fully consider this fact, so we design a special structure,

which allow the mould can run on a min suitable machine,

Unlike the traditional ejection system of plastic molds.

There will be a pull system to move the moving side to non-operation side,

than the product can be picked by robot, 

It greatly saved a lot of cost and energy of customers.

 

We here have a lot of detail information for this kind of traffic cone molds.

If you need any information, please feel free to contact us.

Flip top cap production machine includes plastic mould, injection molding machine and some auxiliary equipment, we want to highlight the difference between the common cap production machine and flip top cap production line. Flip top cap manufacturers are aware that the flip top cap will be easy to break if the top cover not closed before the cap completely cooled, so our production line should solve this problem.

We have two kinds of ways to close the top cover before completely cooled.
1. Close the top cover inside the plastic mould, the flip top cap mould will have automatic closing device, which is what we say in mold closing system or in-mold-closing devise. It will close the top cover before the mould ejection, and this kind of closing system have two options, we can close the top cover with half opening, or closed completely. In the mould structure, the half opening system is much easier, if you need closed completely, we need to mention with mold manufacture, because complex systems will have different price.

2. Of course there is a more simple way, this suit for large production, we have a lid closing machine, after the opening flip top cap produced, the conveyor belt will drive the cap to the closing machine before the cap cooled, and then the machine will securely close the top cover completely.

If you have any inquiry about flip top cap production machine, or if you need any help on flip top cap production, please feel free to contact us.

There are three important systems in injection mold, they are injection system, cooling system and ejection system, in which the cooling system is a most significant step, because the cooling good or bad will affect the quality of the products, the cooling time will affect the mould production, and also affecting production efficiency. So mould manufacturers will optimize injection mould cooling system design.

Injection mould cooling system design generally considers the following factors,

1. Mould waterway design should be independent, core and cavity are symmetrical respectively, if you want to fully cooled, separate some water groups, and use with water manifold collection.

2. The cooling water against the product walls should be uniform, and pay attention to the distance between the product wall and the water channel.

3. Cooling water inlet and outlet must be put at the bottom of the mold or at the non-operation side.

4. The most important thing is to ensure that the cooling water in the channel is turbulent. If the cooling water go through straightly, it cannot take the heat of the steel material, so if the water channel is long and straight, it is better to use a spiral baffle to increase turbulent index.

Buy plastic products according to catalog is very simple, customers can choose their own style and quantity according to the market needs, these products are generally have short delivery time, because the supplier have ready equipment, some suppliers or even be in stock .

For custom-made plastic products, delivery should be longer comparing with above, because the supplier must make molds first before mass production.

How does it works? Do you know?

1.Injection molding step:

Melting the material by the screw high speed turning, and the speed is very important for melt , it is too slow, then the PET material will not be melt properly ,if too fast, then the PET material will be burns. Of course the barrel is important for heating.

2.Injection step:

it means injection the melting material to the mould .it need the injection molding machine provide the injection pressure for help the material full in the mould.
