Daily maintenance of injection molding, routine maintenance of injection molding.
For daily maintenance of injection molding, please pay attention followings:
(1) Examination before using1. Before using the injection molding, we should examine the qualification whether it is suitable for the industry.2. To check the equipment whether it is suitable with injection molding3. The operator should have detailed information of the injection molding performance and be familiar with operation method.
(2) Examining injection molding during the process1. The operation place must be clean. Inside the mould, it should have no dust.2. When using the injection molding, we should obey the rules.3. When try the mould, the first sets of products should be examined carefully.4. During the working process, we should examine the injection molding conditions. If we find some dust in the mould, then we should do the maintenance of the injection molding.
(3) Examination after using1. After using, we should unload the injection mould from the machine under the operating rules.2. When swing the injection mould, we should put down it carefully. After unloading the injection mould, we should clean the injection mould.

back injection molding machine
Now we Dakumar Machinery are developing one new kind of injection molding machine-- back injection molding machine. Back injection molding machine is based on one step molding process. If we use this machine to inejct car interior trim parts, it can be injection one step.
Its advantages of back injection molding machine
It can save cost. Because if it is injected by one step, so we don't need second labour.
The samples of interior trim parts are more beautiful than others.
Application of backing injection molding machine.

Gas-assist injection molding is a process that utilizes an inert gas (normally nitrogen) to create one or more hollow channels within an injection-molded plastic part.
Gas-assist injection molding has been around for well over two decades and many people have had concerns over patent, rights and royalty fees. Within the past few years, some of the original patents have expired. And now, gas-assist injection molding is widely practiced. Design engineers and processors alike are discovering that this technology is an attractive option for certain applications and offers many benefits. It is the responsibility of the manufacturer to ascertain that their practice or technology is not covered by current patents.
Advantages of the gas-assisted injection molding process
1.Reducing stress and warpage
2.Elimination of sink marks
3.Smooth surface
4.Reduced clamp tonnage
5.Elimination of external runners
6.Permitting different wall thickness
7.Cycle time reduction
8.Resin saving

Cap mould, 16 cavities cap mould, lid mould with 16 cavities.
On December 3th,2011, Sino Mould has delivered a 16 cavities cap mould.
The cap is tear-out oil cap, the diameter of cap is 30mm. We use Stavax S420 steel for the mould cavity and core,this steel is mirror steel from Switzerland, tempered with HRC45-52, the polishing can be long lasting, so the molding product is high polish and high quality. We use 16 points Anole hot runner, with German heating elemenst, Anole temperature controller, 18 months guaranteed.
The mould cycle time is very quick. When produce in the Dakumar standard injection molding machine, the cycle time is 8s, when produce in the Dakumar high speed injection molding machine, the cycle time is 4s. So our customer is satisfied with our high quality, quick cycle time and fast delivery time.

The most common types of plastic molding precess used for large scale manufacturing is injection molding process. Injection molding process is a manufacturing process for producing parts from both thermoplastic and thermosetting plastic materials. Material is fed into a heated barrel, mixed, and forced into a mould cavity where it cools and hardens to the configuration of the mould cavity. After a product is designed, usually by an industrial designer or an engineer, moulds are made by a mouldmaker from metal, usually either steel or aluminum, and precision-machined to form the features of the desired part.
Injection molding process is by far the most widely used process of forming thermoplastic materials. It is also one of the oldest. Currently injection molding process accounts for 30% of all plastics resin consumption. Since raw material can be converted by a single procedure, injection moulding is suitable for mass production of plastics articles and automated one-step production of complex geometries. In most cases, finishing in not necessary. Typical products include toys, automotive parts, household articles, and consumer electronics goods.
A typical injection molding process consists of five phases:
1. Injection or molding filling
2. Packing or compression
3. Holding
4. Cooling
5. Part ejection

The injection molding machine is always working for
24 hours one day. It is usually not stopped. For the
injection molding machines which is in the situation
of working for long time. For such injection molding
machines, we must do good injection molding machine
maintenance. We should make effort that find and solve
problems before machine goes something wrong that is
injection molding machine maintenance. Otherwise,
when the machine have problems, we must stop production.
It will seriously effect production and delay delivery
time. Therefore, injection molding machine
maintenanceis very important.
For injection molding machine maintenance, it should be
proceed in the following aspects.
1. Injection molding machine maintenance-- electric equipment maintenance
2. Injection molding machine maintenance-- hydraulic system maintenance
3. Injection molding machine maintenance-- clamping part maintenance
4. Injection molding machine maintenance-- injection part maintenance
If you have any question of injection

Injection molding machine hydraulic system maintenance is very important. We should consider it into six points. In this passage, i will tell you how to maintain injection machine hydraulic system. The hydraulic oil temperature of injection molding machine should be kept during 30-50 degree. If the temperatue overpassed 60 degree, it will be occur following problems.
1. The hydraulic oil will be oxidation and then go bad.
2. Hydraulic oil will be have little viscosity and then will damage the pump.
3. It will increase the speed of aging rate of oil seal.
Then How to maintain injection machine hydraulic system?
1. Every 6 months, we should take apart the cooling oil parts to clean it.
2. We should change hydraulic oil every 3000-4000 shots of injection molding machine.
If you have any suggestion of how to maintain injection machine hydraulic system, please feel free to contact me.
