Rapid prototyping play a very important role in China product development
Study shows that 80% of the production cost is determined at the design stage. Therefore, the design stage is of great importance to product cost control. Rapid prototyping constitutes an important part in the industrial design process. From the fully manual prototyping (hand sampling) to the semi-mechanical prototyping, then to the modern 3D printing of prototypes, the progress epitomes the technological progress of the modern manufacturing industry. Among them, though Rapid prototyping is an advanced supportive design technique, it doesn’t receive enough attention. It has been proved th Rapid prototyping not only plays a very important role in product design decision, but is also an effective tool for protecting product information and marketing. Now, let’s talk about the importance of … Read more
Different mold cooling channel design cause different cooling effect
Many believes that the special-shaped cooling channel is not effective at all, but is a kind of deceptive technology! As a matter of fact, the point is not that the special-shaped cooling channel is not effective, but where you choose to place the cooling channel is still arguable. Let’s take a look at the example below: Figure 1 shows the same part, coming with special-shaped cooling channels designed by different designers. Although all of them adopt the special-shaped design, they perform differently with regard to mold temperature improvement. See Figure 2, let’s verify this using the CAE software. We can find that some of the designs give a great performance as shown in Figure 4, but some others are not … Read more
Types of Food Grade Plastic Materials
PET PET Usually, this plastic is used in the production of plastic bottles, beverage bottles and the like. The plastic water bottles and carbonated beverage bottles people often buy are packaging products made from PET, which is a food-grade safe plastic material. Potential Risks: PET is only suitable for the packaging of room temperature or cold drinks, rather than overheated food. If the temperature is too high, the bottle will release toxic substances, which may cause cancer. If the PET bottle is in service for a long time, it will automatically release toxic substances, so the plastic beverage bottles should be disposed right away after use, and should not be used to contain other foods for a long time, so … Read more
How to control the cost of plastic injection molding?
The cost control of plastic injection molding also involves many factors. It must be controlled from the equipment, application process, raw material, as well as management and technology to achieve the optimal efficiency at the lowest cost. Tools and Components Control: Tools – All screws, nuts, nylon hoses and hose clamps, etc. in the packaging workshop must be controlled with a corresponding method, or great waste will be caused! Mold Application Control: Production Process: Appropriate clamping pressure during the adjustment process – It is appropriate as long as the product meets the requirements, and the clamping force is able to ensure that the injection pressure does not force the core and the cavity open to cause flashing. The ejection … Read more
Surface finish of plastic injection molding product
Different physical and chemical properties of the polymer blends, as well as the different parameters of the plastic injection molding process cause the surface finish on the plastic composites to vary greatly. For a plastic injection molding service provider that offers custom-made products, the first goal is to work in collaboration with the client to determine the importance of surface finish for the exterior appearance, as well as the performance of the injection molded product, or to be specific, is the final product an eye-catching piece or simply a functional one? Your answer to this question determines the choice of material and the option of surface finish, based on which the plastic injection molding process is set, and the secondary finishing operations … Read more
China mold manufacturing business status compare to other countries
Over the past decade or so, China mold manufacturing technology has made a qualitative leap, and the mold manufacturing industry has grown rapidly from small to large, making China one of the biggest mold manufacturing countries in the world. Along with the development of China’s automobile industry, the rise of domestic auto brands to the middle and high-end market segments, and the emergence of new energy vehicles, the market has put forward new demands for us, which requires us to move from low-end molds to high-end molds, and from a large mold manufacturing country to a mold powerhouse. At present, the mold production value of the six mold manufacturing countries, i.e., China, the US, Japan, Germany, South Korea and Italy, … Read more
Moldflow Analysis Report for plastic injection molding
Moldflow analysis is the plastic injection molding simulation software that obtains data and results through the computer-aided simulation to simulate the plastic injection molding process, based on which, the feasibility of the mold solution is to be evaluated, in a bid to improve mold and product designs. Wall thickness and mesh statistics in moldflow analysis Thickness are uniformed Plastic material information Initial Nozzle/Gate Locations and Circuit Filling The filling process is balance Distortion, all effects at Z Component In this plot a scale factor of 2X was added to overstate the magnitude of the warpage to make the trends easier to understand。 1) 4 gates injection Deflection of Z direction is large NG 2)2 gates injection Deflection of Z direction … Read more
Quests to know the plastic injection mold price?
Do you have engineering design or physic samples? if you provide drawing, the most mold factories prefer 3D data in step or IGES format. If the design is complicated or large, the mold design should also be complicated and more cost. if you have physical samples, the mold factory will copy it and made the mold for you. What kind of plastic materials will you use for product? their price and characters are totally different when you choose different plastic resins. How many cavities will the injection mold have? how many parts will it make per shot(cycle)?it depends on the quantity you forcast to produce. if you plan to produce a huge quantity, then need more cavities in the mold. … Read more
Factors Affect Plastic Injection Molding Cost
The involvement in a plastic injection molding project will surely enable you to understand that the mold can easily become the most expensive part in a project. Among the multiple factors that affect the cost of a plastic injection molding product, the top three ones are undoubtedly the dimensions and complexity of the part, the quantity of the part, as well as the effort required to build the plastic injection mold. As we know, the cost of all manufactured products is dependent on that of the raw material and the labor required. Therefore, the cost of a plastic injection molding product is also dependent on the costs of the plastic material and the labor involved throughout the production process. Here, … Read more
How to choose cost effective plastic injection molding supplier from China?
What kind of injection molding supplier is a better choice? With regard to this question, people believe that it depends on the specific situation. When considered from the only perspective of factory size, it is better that you choose the larger one, because a large size is often an synonym of strength, meaning that the comprehensive strength of the factory is better. Besides, the size also indirectly reflects how popular the factory is among customers! However, conversely, the larger the size, the higher the management cost is, so there will not be noticeable cost advantages. It is very important to know whether the injection molding supplier you choose regards you as an important customer, i.e., whether you are important to them. If … Read more
