She told us why she chose Danke Mold at that time: “I am a student of Zhuhai College of Jilin University, and I major in International Economics and Trades. When I first met Danke Mold, I was deeply attracted by the professionalism and challenge of Danke Mold.” Yes, Danke Mold is a professional and high-quality plastic injection molding manufacturer, and quick-turn manufacturing company in southern China. We provide plastic injection molding, rapid tooling, rapid prototyping from concept prototype to volume production. “You know what, my major is very similar to the job requirements of Danke Mold, and I have never been exposed to any knowledge related to the company’s business operations, such as quick-turn injection molding. I think this is a great learning opportunity,” she said. Customers we’ve worked with know that, our professional project managers, with strong engineering backgrounds and rich project management experiences, served western customers for 10 years. We deeply understand customers’ needs, provide professional DFM analysis and customer-oriented manufacturing solutions, for the best approach of custom parts manufacturing. No wonder Tabby wants to learn something new here! Tabby has a long way to go before she can keep up with her seniors, adjust to the job and meet her boss’s expectations. She needs to learn a lot of knowledge related to injection molding or rapid tooling in her spared time and embody the results of her study at work. Of course, Tabby also knows the value of combining work and leisure, and will relieve the pressure by doing some small crafts or reading novels. And we hope that after the training, Tabby can become the project manager we expect and be competent for this job. Or at least grow into a project manager who meets the following requirements: Tabby should communicate with client directly, arrange the job once the project is confirmed, prepare the prototype BOM to the engineer and whole-process tracking project. We hope Tabby can grow with Danke Mold!Stay tuned for more information with email@example.com
Injection Mold polishing is primarily a manual process requiring a high level of skill and knowledge. Mold polishing is perhaps the only operation that is not able to be automated, when all the CNC machining, EDM machining, surface grinding, and wire cutting are completed, the mold polisher is the one who puts the final appearance on the molding surface.Before the polishing process, we have to know that there are some factors that affect the polishability.1) Tool steel quality. Different grades of tool steels will require a different polishing techniques. For example: it takes more time to polish 420 stainless steel than H13 steel.2) Heat treatment. A case-hardening steel which has been overcarburized is likely to have an unsuitable structure for polishing.3) Polishing technique. Different polishers have slightly different ways to polish which they have developed during years of practice. The ultimate guide of a good polisher is one who can get the required finish on time at a reasonable price.There are a number of finishes available to mold makers and the final finish depends upon the plastic part requirements."Stoned” finish: This is the most basic type of finish, which uses stone abrasives to get a matt finish. They range from 100 grit to 1200 grit. This is the cheapest & quickest form of polishing. Normally used to remove machining marks, so as to make the ejection easier during molding. “Paper” finishes: This is essentially a fine abrasive attached to paper which is used after stoning to get some level of gloss on the mold tool surface. The plastic part will also replicate this same level of gloss on its surface。Mirror polish: This is the most expensive and time-consuming type of finish to achieve and needs the first 2 stages (stoning and papering) to be completed before mirror polishing can begin. Diamond paste is the most common abrasive agent used in polishing. Optimum performance is obtained with the right paste, on the right polishing tool.Above all, cleanliness in every step of the polishing operation is of such great importance that it cannot be overemphasized. Mold polishing can cause the profits to quickly disappear if unnecessary time is wasted on over-polishing or making up for poor surface finishes from the milling, grinding or EDM operations. Each machining operation must have surface finish requirements in order to avoid this problem.Therefore, it is necessary to know your customer’s minimum requirement for their product. The best way to do this is to find several sample parts of different finishes and let your customer to approve the minimum requirement. This approved sample can then be passed on to the mold polisher so he can replicate the required finish. Also, knowing if the polished finish is for functional or cosmetic reasons helps in deciding the type of finish.Why we strive for good surface finish for the injection mold? Generally, there are some advantages with high surface finish, including：• Obtain good quality surface finish for the molding plastic parts.• Easier ejection of the plastic parts from the molding tool• Reduced risk of local corrosion• Reduced risk of fracture or cracking due to temporary over loading or pure fatigueMold polishing usually determines the quality of the work of an injection mold surface finish, and this manual process can quickly consume profits. The injection mold making may have been done well, and the mold making process may be efficient, but if the surface finish is wrong, the part is rejected.Usually the project manager may be able to discuss changing the surface finish in order to keep costs as low as possible. The same to over-compensate in order to be on the safe side can occur from the customer’s end as well. For this reason it is well worth the effort to communicate with your customer to find out the actual surface finish they need.If you were working on a tooling or injection molding project, try to contact Danke Mold for some manufacturing thoughts or cost ideas.

CHIAPLAS 2019, the 33rd International Exhibition on Plastics and Rubber Industries, started on May 21st at China Import and Export Complex, Guangzhou. Danke Mold, a professional and high-quality plastic injection molding & quick-turn manufacturing company arrived in the exhibition hall that very day. We were here to learn the latest technology of Plastics and Rubber Industries and to find some suitable partners. It was nearly 11:00 am when we arrived at the exhibition from Zhongshan. Compare with the previous trip----Asiamold 2019, only six members came to CHINAPLAS 2019 of this time: Joe Deng, Jade Du, Jack Liu, Angela Du, Bennett Liu, and Tabby Tan.With the theme of “Innovation is Key to the Future”, the show housed more than 3,500 exhibitions from 40 countries and regions in an over 250,000sqm of exhibition area, showcased latest products and solutions. This year, CHINAPLAS comprised 20 theme zones to facilitate the successful sourcing of buyers. The show was full of variety, in the limited time we found a few major highlights: smart manufacturing continues to take center-stage, circular economy promoted to a prime position, the potential of high-tech medical plastics further unlocked and game-changing materials for the automotive sector.From our own point of view, although Danke Mold has a mutual process for quick-turn manufacturing and high-quality plastic injection molding, we still need to learn from the exhibitors. Firstly, we can increase the variety or stock of raw materials in our injection molding line. Secondly, introduce more advanced injection molding machinery to compress the delivery cycle required for finished products. Thirdly, or we can introduce technology to achieve the goal, such as the Mold and Inner Packing Process. Fourthly, Danke Mold may consider entering the field of 3D printing and using the most advanced 3D printing technology after Danke Mold grows. Finally, of course we can not forget to contribute to the protection of the environment, we believe that the use of recycling technology and recycled plastic can bring us the greater development and opportunities.What a fruitful and tired day! Danke Mold will serve our customers with a more brand-new attitude after this CHINAPLAS 2019, as a high-quality injection molding manufacturer and quick-turn injection molding maker!

Injection mold design is an important part of plastic product development. As a mold maker and injection molding factory, in order to improve the quality of parts, enhance tools performance and save manufacturing cost, we always keep thinking how to optimize the design and fabricating level of the molds. During design process, it is necessary to make a choice for the gate position and quantity, so as to control the material filling process. CAE analysis is able to provide several advices for designer to decide the gate location, and give relevant comments according it’s influence. Optimizing the gate position is essentially make verify the proper gate position and technological parameter to produce best plastic part. Take the injection molding systems as example, designer should divide the feeding system into several steps, then complete and optimize the whole system design step by step: 1) Initial confirmation of the design proposal. With the help from software design tool, designer does synthetic judgments and calculation to the reference information, based information and regularities, to confirm the hydraulic fluid distribution of feed system, determine the gate type which can raise the feeding speed, gate location and quantity in detail. 2) In the modifying and adjusting process, designer needs to adjust the route of fluid go through and reduce the area of path to raise the feeding speed of material according to manufacturing requirement and design purpose. Optimize components precision as per the gate quantity, design the exterior of the mold as per the gate type like direct gate, rectangle gate, pin-point gate, tunnel gate, etc. 3) Collect/summarize the data/information above and input to the design model, inspected by the feeding system, check if there’s any error for the gate design. If a balanced filling mode can be promised by the design of gate location, then it will make the pressure, temperature and the distribution of shrinkage even, so the part quality will be better. Therefore, the choice of gate position is usually be determined by flow balance or not. The key issue of injection mold design work is feed system design the cooling classify system design, we will talk about the latter in the future.If you were working on a tooling or injection molding project, try to contact Danke Mold for some manufacturing thoughts or cost ideas.
