SINO is leading preform mould manufacturer in China. It has been supplying preform mould for decades. It features as follows:
1. large production capacity
1.1 multi Cavity NO.
We could manufacture to 96 cavities.
1.2 short Cycle time
To shorten cycle time, there are three aspects:
Firstly, cooling system. Our cooling system for preform mould is effective. The core, the cavity and the screw all have cooling waterline. The size of the channel and the waterline number are adequate and the design is very good. Only with effective cooling system, can shorter cycle time be possible.
Secondly, valve gate system. Valve gate is adopted mostly for the reason of quality. But it has another merit, to shorten the cycle time. It closes the gate at the end stage of pressure holding period. In this way, cycle time is shortened.
Thirdly, we could use robot system(more details, please read article: Robot system from SINO), it reducing the cycle time by outside cooling.
2. good quality and high efficiency
2.1 Design, mould flow analysis. our structure design for preform mould is keep updating and advanced. we are rigirous in inspection into mould design which is necessary to both quality and efficiency.
2.2 Precise machines. To avoid size error and decentration, we use high precision NC lathe. We maintain the machine to avoid overwearing of the tools which may also cause size problem.
2.3 Valve gate and steel. We use valve gate of good brand and S136 as steel for core and cavity. For preform mould, valve gate is necessary. It allows bigger gate as well as good appearance and with valve gate, the bottom of the bottle is safer.
2.4 Standard manufacturing. The cavities are numbered, and independent to each other. We have standard production line to manufacture the parts. If standard parts are needed, they will be delivered to the customers within 3 work days. We have efficient solution.
3. one-stop preform mould service
We offer service from preform design to preform mould manufacturing and after-sales service. If you only have a bottle, we can design for your preform. And we offer technical support to your factory.
Sino is top PET preform mould manufacturer in China. We offer not only a mould, but a preform mould solution for your business.

Blowing moulding is a main way of moulding in container field and recently, in industrial area, it is also developing.
There are two kinds of blowing moulding, injection

 
 

 

blowing moulding and extrusion blowing moulding. It is easy to tell between them. Injection blowing leaves a small round gate mark at the bottom center. Extrusion blowing mould leaves a parting line separating the product into two halves.
For different kinds of bottles, we choose different blowing moulding type. The material is also very important.
PET is very suitable to make preform and transparent bottles. To produce PET bottles, we usually adopt injection blowing moulding.
Injection blowing moulding has two steps: preform moulding and blowing moulding. So it needs two moulds, two machines. That means higher cost. So why should we choose injection blowing moulding?
The advantage of injection blowing moulding:
1. higher precision of screw, higher precision of size. For beverage bottles, medicine bottles, they are of great advantage to avoid pollution.
2. No waste of material.
3. The appearance looks more beautiful.
 

Sino PK is leading chinese PET preform mould manufacturer, it could offer customers whole PET bottle production line. It has decades of experience in PET preform mould manufacturing and keep updating its technology. It offers customers not only a mould, but a fine solution to reach customers' production requirements.

Professional plastic cutlery molds manufacturer in china. When developing plastic cutlery molds, it is more profitable to make plastic molds with plastic spoon, plastic knife and plastic fork together in one mold. The plastic injection mold for disposable tableware can be in both round shape and square shape. If with semi hot runner, it is better to design mold in round shape, as the plastic material flow is more even and it is less runner waste.

Due to large quantity needed for disposable plastic spoon, fork and knife, the plastic cutlery molds should be designed with very good cooling channel, to make plastic cutlery molds achieve fasted molding cycle time. Normally speaking, with 24 cavities plastic spoon, fork and knife molds, the cycle time must less than 8 seconds.
For plastic cutlery injection molding production, it is better to use high speed injection molding machine to operate. High speed injection molding machines can helps you save several seconds on plastic material injection. With different mold cavities, high injection molding machine for normal plastic cutleries molds could be DKM 50 to DKM 380ton.
For cutlery mold inquiry, pls send mails to sino_mould@hotmail.com or skype at sino.group01

Modern mold processing industry is developing rapidly, the mold industry, market competition is more intense, the customer requirements of mold processing cycle is shortened, also they have more and more high quality requirement.

I think quality control can be divided into four big aspects: design quality control, mould tooling quality control, mould inspection and mould trial quality control.

1. For the design quality control period, firstly experienced designers and engineers hold up a design proposal meeting to decide the mould injection gate and mould structure, etc.

Secondly, mold designer should fully understand the plastic product technical requirements, so that when he design the mould must meet the plastic product technical requirements.

Thirdly, when design the mould should take the mold tooling into consideration to ensure the design is reasonable and economical.

Fourthly, there should have reasonable measures to reduce the mistakes to the minimum.

Fifth, there should have some training courses for designers and technical person. In the past years, we get several patent designs for our four cavity crate mould and automatic closing flip-top cap mould, etc. We are the first company to make such moulds in China.

2. In the process of mold manufacturing, mold manufacturing equipment is the important content of mould tooling quality control. The tooling equipment operators should do the daily equipment maintenance. To choose the mould tooling equipment should ensure the mould precision. Our company equipped with the best tooling machines, we imported tooling equipments from Japan and Italy. Our precision wire cutting tolerance can reach to ±0.5um.

Secondly, should strictly control the mould steel and standard parts quality so to avoid more waste during mould manufacturing.

3. Inspection is very important during the mould making. The inspections including steel inspection, design inspection, tooling process detection, mould assemble inspection and so on. For some high precision mould, we will adopt three-coordinate inspection after each tooling process completed.
4. Mould trial is also a good way for quality control. When the mould is ready for shipment, we will run each mould for more than two hours simulation production, so that if there's anything wrong we can find it out and fix it before the mould shipped to customer's factory.


In the fast developed society, only good quality is not enough. Customer is also pursuit fast delivery mould. As an old saying, time is money. So time control is also very important during mould manufacturing.

We have a strong and experienced engineering team to follow-up each project, they will update mould manufacturing status each 10 days and when the mould manufacturing face some dificulties, experienced engineers can provide optimal solutions timely, so it can save a lot of time.

For plastic injection mold design, when should us can make the mold design in solid, and for which condition it is good for making mold inserts?

Usually mold design in solid will be more stronger then mold in inserts. But mould with inserts would be more used in the following conditions:
Mould is with very complex structure, in this way, to design in inserts is better for solid, it is better for machining.
mold area which is not ok for making coolings, we can design in inserts, maybe to use cube to help for fast cycle.
Mould in inserts that can help in solving the air venting problem
Design mold in inserts, like bucket moulds for hot runner gate system, it is goof for future mold maintenance.
We offer injection molds with good mould design, welcome to contact with us.
