Plastic Pallet Making Machine

Plastic Pallet Making Machine


Plastic pallet making machines supplier-Sino Holdings Group, is the professional plastic production molding lines exporter in China, with the rich experience for plastic pallet production molding machines. 

At the early years, there are not much mold makers who can manufacture pallet molds, because the mold is with larger size, there is limit on the mold tooling machines, many customers bought pallet molds with the cost of 350,000 USD or even more from Taiwan, Japan or European markets. Adding up the injection machine cost, not every customer who can afford this production line. So, the normal ways to one company order pallet molds and put the molds to another factory who owned the big injection machine, or use a samller injection machine for half pallet then weld together to get a complete pallet.

In passed years, Sino Holdings groupe with help of Sino Mould and DAKUMAR Machinery, have accumulated a lot experience for how to set up a plastic pallet production line at most economical ways.We  knew well how to control the pallet mold cost and can offer the tailor-made plastic pallet making machines as the pallets production requirements. We are thinking ways to make some concessions to our customers to support them as the investment is much bigger than chair or table production lines. For example, one 1200x1000x150 mm pallet mold, double deck, 4 entries, product weight is around 15kg,the cost of Sino Mould is much lower than Taiwan mold or european molds, just half of that cost, some pallet molds only cost 1/3 of that.  Also, we can supply the making machines like DAKUMAR 2600 TON servo power injection machine,top entry robot,auto loader,mixer,water chiller,crusher and cooling tower...everything needed for the plastic pallet production line.

Welcome to contact us for plastic pallet making machines , Sino holdings Group can offer turnkey project service for pallets molding lines,we ensure that you dont need to waste time and money to contact different suppliers,no worries for communications of different suppliers, no worries for after sales service,Sino Holdings will help to start from Zero to a "money printer" factory

Turbine Mould|Air Conditioning Turbine Mould

Turbine are widely used in industrial air cooler, air conditioners, air cooling devices, air venting device, and some large machinery industries. 

The old turbines is not made by plastic injection molding, most of them are made by metal castings, and combined together by welding, In recent year, most and most turbine fans manufacturers required to make injection molds for saving cost and environmental protection. Due to its complex structure, mold design and processing procedure is relatively complex, without high precision machining tools and experience mold technicians, it is very hard to finish a qualified turbine mould.

Sino Mould is skilled plastic turbine molds maker in China, and we have business cooperation with biggest fans making factory-YILIDA, they supplied fans to York air conditioner,Gree air conditioner, and top famous air conditioning manufacturing. Meantime, we are the mold supplier for many air conditioners makers, they also need turbine molds or turbines, we can offer molds to them and also can offer the finished fans for them, we do injection working,welding work, balancing, testing and deliver the final fans for them.The mold part dimension tolerance required ±0.01 mm,the mold steel is DIN1.2344 for core and sliders, P20 for mold base, YUDO hot runner, Magnetic hydraulic cylinder for controlling the stroke, ejection is collapsible core pulling +ejectors, mold warranty is 500,000 shots.

Turbine mould are widely used in air venting system, air cooling system, if you are in this business line, welcome to contact us for mold price inquiry or any technical issues for turbine mold or other fan Mould.

Air Conditioner Fan Mould

Air Conditioner Fan Mould, including tangential Fan mould, turbine fan molds, and Sino Mould also made other fan moulds like air venting fan molds, pedestal fan blade molds, there are many types of fan molds, with different functions, different types and different materials.

For the air conditioner tangertial fan, it needs three steps to get the final fans.
Normally, the fan need three molds, the plastic material is AS+30%GF,then conbined three parts by ultrasonic welding machine,final step is balancing and adding clips to refine the balancing to reduce the noise.

For the air conditioner turbine fan,there are  integral fan and split fan,integal fan with complicated mold structure, and split fan need to be combined by welding machine. They have their own strengths and weaknesses.

Sino Mould is the high quality home appliance mould making company in China, can design and manufacture all kinds of air conditioner fan molds, is long term cooperation partner for air conditioning industries, air cooling devices manufaturers, like York, Midea, Wheelpool... Many famous home appliance makers need to buy the fan molds.

How to make sure that the air conditioner fan mold with balanced ejection?
The key point for the air conditioner fan mould is we need very even injection points to keep the blade moulds' plastic filling are in the same pressure and same distances.  In the same time, we have to know that the moulding area's different temperature will caused the filling not even. This will cause the fan blade parts'gravity point will not in the center, so when the blade turning, there are ugly noise. 

We know how to make even injection and cooling effects on the moulding areas are the same to make sure the fans come out from the molds will be balance, and the fans will run quietly or lower noisy, The material of fans can be PP, ABS, HIPS, PA 6+25%GF,AS+25%GF, the mold steel for core and cavity can be S136, NAK80, DIN.12738, DIN.12344 according to the fan's material and fan's applications. 

If you need fan molds or want to know more about air conditioner fan molds, welcome to contact us.

PC Plastics Application-Home Appliance Molds

PC plastic material is widely used in lens mold, displayer molds or panel molds of home appliance and drawers  molds of freezer. When making the mold design for PC part, we should know well about its injection molding features otherwise it is hard to deliver the qualified samples for customers' approval.

1, Preparation before injection:

Water absorption of PC plastic materials is large, the PC ram material must be dry before injection, pure PC shoule be drying in 120 ℃, modified PC Chips with a temperature of 110 ℃ dried for more than 4 hours. Drying time can not exceed 10 hours. Generally available air extrusion method can determine whether the material is sufficient drying. 

2, Injection molding machine selection:

PC plastic products due to cost and other aspects, the use of modified materials, particularly electrical products, should also increase the fire resistance, in the flame-retardant PC alloy products and other plastic molding,plastics mixing system of injection molding machines required good resistance to corrosion, conventional plasticizing screw is difficult to achieve, So, PC screw was suggested to make PC parts.Normally, we will use DAKUMAR Injection  Machine PC screw injection machine.

3, Mold design and Injection gate location selection:

Common mold temperature of 80-100 ℃, with fiberglass is 100-130 ℃, small articles can use point gate, and gate depth should be 70% of the thickest parts. For freezer drawer molds, we will used hot runner valve gate, the hot runner system can be YUDO, HASKY,MOLDMASTER ...and of the other  cold runner gate is edge gate or rectangular gate. Gate is bigger, the injection is better in order to reduce PC plastic flowing resistance through the gate. Air vent slots depth should be less than 0.03-0.06mm, the flow path as short and round, draft angle is is generally about 30'-1.

4, Melt temperature:

 General PC plastics processing temperature of 270-320 ℃, some modified or low molecular weight PC plastic materials for the 230-270 ℃.

5. Injection speed:

Common with relatively fast speed injection molding, like electrical switches , Slow - rapid forming.

Long residence time at high temperature in the injection machine barrel, the material will be degraded, put CO2, the material turns yellow. 

Do not use LDPE, POM, ABS or PA clean up barrel, please use PS !

Hope the PC Plastics Application-Home Appliance Molds is useful for you, Sino Mould is good at design and manufacturing home appliance molds.
