nice injection gate for mouldt|he most importance fluence for nice injection gate|Sino Mould

Nice injection gate is the important issue for the preform mould. Gate mark too long is the main  issue that influenced the preform. To solve this issue we check out the reasons and also get the solution from them . Here are the solution ensure the  Preform mould nice injection gate

Long gate mark means the preform have too long raw material. Probably reasons can be divided into four parts. The first cause is that the injection gate is too cold when the valve is closed. To avoid this matter, we should first increase the injection nozzle temperature. And also we longer the valve injection time.

The second reason is that the valve abnormally close. When facing this issue, we should do the follows.

1. Increase the mould sub runner temperature.
2. Check whether the hydraulic pressure is suitable.
3.clear up all the part ,nozzle,manifold, connect part..
The most important issue is to ensure the seal ring, whether it is ok.

The third reason is that the raw material viscosity is too high, in this condition we should increase the material temperature to reduce the flowing material viscosity. and of course the raw material match the  preform is the most important idea. The last reason is that the flowing material heating is too lower , can not flowing smoothly. When this phenomena happens we should first increase the runner temperature and the nozzle tip temperature.

Sino provide u Preform mould with nice injection gate. Any interested ,please contact me freely .

mould life|how to ensure the mould life|sino mould

Mould is relatively expensive technological equipment, the mold manufacturing expense accounts for about 10% -30% of the cost of the products , and the mould life will directly affect the cost of the product.In the case of mass production, the service life of mould is particularly important. General in the mold design stage should clear the mould of the production batch type or the total number of mold production parts, namely mould design life.Different mold with different damage form.but on the whole, the work surface damage are mainly in the form of friction damage and plastic deformation, cracking, fatigue damage and injury.

The main factors affecting the muld life has the following kinds:

1.Mould Structure
 Reasonable mould structure helps to improve the capacity of the mould, reduce mold endure loading level. For example,Reliable guidance mechanism can avoid nicking each other between the core and cavity.

2.Mould Material
 According to the production quantity, we will choose the best mould materials.High production with higher requirements for the mould life, so we should choose strong bearing capacity, high long service life material. In addition, we should pay attention to the mold material metallurgy quality may cause the process defects and effects for the bearing capacity of the work, and take the necessary measures to make up for the inadequacy of the metallurgical quality, to improve mould life.

3.Mould Processing
 The defects of mold parts machining, E.D.M processing and forging, pretreatment, quench hardening, surface treatment will cause the is to mould wear resistance, resistance to bite ability, and a significant impact on the fracture resistance.

4.Mould Working Condition
 When the mold work, using the device's accuracy and stiffness, lubrication condition, the pretreatment of the processed material status, mould preheating and cooling conditions will have an effect on mould life.

Sino can guarantee the long mould life,and we can do the best quality plastic injection mould,welcome to contact with us.

plsatic syringe mould|Best quality plastic syringe mould in China|Sino Mould

There have many kinds of medical machinery moulds,such as the big infusion mould, tube mould, syringe mould, etc., As started with mould factory,Sino as the top 10 nation’s mould factory , also has the best technology and experience in this field.

About before two weeks, has a foreign medical enterprises to looking for our help.they want to make syringe mould and the customer’s requirement is not the same as the common product, they request do test mould, and it need to send United States after 18 months of inspection need,after getting certification of qualified book,then will open mold to start production.

This product is not the same as ordinary product appearance, especially the small aperture is small, need to be 5-10 mm in diameter. Before they find ourcompany,they also tried to consult several other mold factories, they are all back to the award of the order. Because at the present, in domestic can reach the standard is few and far between. It is also can't do it at home and abroad, but Sino mould can reach 3 mm in diameter.

We have rich experience in syringe mould , especially for the PET, PS injection  hot runner system, at the same time with high-precision processing equipment, technology and management, enables us to successfully produce multi-cavity mold. If you need syringe mould, or any other information need to consulting, welcome to contact us. We r looking forward to cooperating with you.
