How to control injection molding time

In the process of injection molding, the time control system is very important, which will affect the quality of the whole finished product. If you want to do well in injection molding processing, in addition to skilled operation, you should also have the ability to control the processing time. Because if there is no time to control some research steps, we may find that there are many problems in the product information produced. So in what aspects should we […]

What factors will affect the accuracy of injection mold processing

How can we effectively improve the precision management of our injection mold during processing. First of all, we must know what problems affect the production and processing accuracy of injection mold.
1. Dimensional accuracy
It refers to the actual working dimension of machined parts and the tolerance size and range of parts.
Accuracy is controlled by dimensional tolerance. Dimensional tolerance is the allowable deviation of part size in the cutting process. When the basic dimensions are the same, the smaller the dimensional […]

Specific requirements for injection mold maintenance

1. When replacing mold parts, recognize that the parts to be replaced are qualified;
2. Each component shall be gently knocked and slowly pressed during disassembly and installation;
3. During the installation of die inserts, the cooperative gap shall be recognized as qualified;
4. Prevent the surface of parts from warping, scratching, pits, dross, deformity, rust and other conditions;
5. If any parts are replaced, communicate and acknowledge with the mold design department in time. Pay attention to the balance of each part […]

How many suggestions did we mention for mold protection?

If there is no effective mold protection, the mold will be damaged. We gives you the following suggestions:
When disassembling the mold, avoid bumping and drenching, and move stably.
Spray hot mold, and then spray a small amount of release agent.
Conduct a comprehensive inspection of the mold and carry out anti rust treatment: carefully wipe out the moisture and sundries in the cavity, core, ejector and row position, and spray anti rust agent and grease on the plastic mold.
The maintenance of […]

How does the development of mold technology affect the mold?

The development of mold technology should serve the requirements of “short delivery time”, “high precision”, “good quality” and “low price” of mold products.
Die CAD / CAM / CAE technology is the development direction of die design and manufacturing.
With the development and progress of microcomputer software, the conditions for popularizing CAD / CAM / CAE technology have been basically mature. Enterprises will strengthen CAD / CAM technology training and technical services; Further expand the application scope of CAE technology.
The degree […]

Ingenious design of lifter in injection mold processing plant — solving the problem of poor assembly

The designers of the injection mold processing plant found that if there is no preset gap in the mold design, it will lead to many problems such as poor assembly and needle breakage and needle burning when ejecting the mold. So how do the mold design engineers of Dj molding solve this problem?
 
1. Design skills for connecting lifter: since there is no allowance for the large inclined plane of this kind of lifter, and there is no allowance for […]

How to improve the service life of molds? Dj molding, who has more than 10 years of experience in mold industry tells you!

No matter what object has a certain service life, the glue coated mold is no exception. When it is used to a certain extent, the mold will fail and need to be opened to produce a new mold. The service life of mold is affected by many factors. Only the  mold factory with a complete understanding of these factors can suit the remedy to the case and produce a mold with a longer service life.
 
With the rapid development of […]

What are the aesthetic applications in the product design of beauty instrument injection molding production company?

Only when modern products have good quality characteristics can they meet the increasing aesthetic requirements of consumers. For the product design of beauty instrument injection molding company, it has always been our pursuit and goal to present products to customers in a more beautiful attitude.
 
Therefore, when designing products, our designers integrate the content and processing methods of aesthetic art into the whole product creation, and comprehensively reflect the physical beauty, linear beauty and color beauty of products by using […]

What are the precautions for mold test before processing in injection mold processing plant?

The injection mold processing plant shall increase the mold temperature, select the appropriate mold temperature control machine according to the performance of the raw materials used for the products and the size of the plastic mold, and increase the mold temperature to the temperature required for production. After the mold temperature is increased, the action of each part must be checked again, because the mold clamping phenomenon may be caused by the thermal expansion of steel, so the sliding […]

Injection mold factory’s know-how to do well in products — paying attention to injection molding process

Some products of the injection mold factory are molded with PC (polycarbonate) or PC + ABS materials. Due to the poor fluidity of PC, the process is usually filled with high mold temperature and high material temperature: the gate used is usually point gate, and graded injection molding is required to find the gate position and injection pressure maintaining switching position, It will be very helpful to solve the gate gas mark and flash anomaly.
 
Therefore, if our injection mold […]
