What points should be considered when design the precision mold?



As we know, the precision mold plays an important role in the injection molding manufacturing, so we need to know what should be considered when design the precision mold,let’s discuss them together:
◊ Know the requirement of the product
As a mold designer, you need to know the requirements of the product, which is also the source of precision mold design. Therefore, the designer must be well known the requirements for the product,such as the shape and dimensional accuracy of the molded article, the flowing direction of the resin, the transmission of the injection pressure, and the solidification of the filled resin.
◊ The characteristics of the molded product
We need a systematic list of the properties of the molded article, mainly the material, the shape of the molded article, and these will have an effect on some details design of the mold
◊ The structure of the mold
The structure of the precision mold is different from the conventional plastic mold and the structural design schemes will be different. There may be several structural design schemes for ordinary molds, but for precision molds,there may have a certain influences on some structures . Therefore, some precision mold structure schemes may be very demanding. The mainly consideration is the mold operation on the product .
◊The rigidity and strength of the mold
 My personal experience is that the rigidity of the mold is very important. I often see that some mold base and inner mold materials are very thin. I can only say that maybe this mold can be used to product manufacturing, but the problems on products have close relationship to the strength, sometimes it is difficult to find. If it is saying that the strength of the mold is to maintain the mold will not break, I think this is a very unreasonable idea, it can be regarded as lack of the experience in mold design.
◊The glue inlet and the cross rubber channel
The glue inlet and the cross rubber channel are important factors in controlling the product. The precision mold has certain requirements on the way of glue feeding the product, making glue point well will have an imaginary effect on the product
◊ The temperature adjustment and cooling system
The mold temperature adjustment system. the temperature of the mold should be uniform. It is necessary to set the temperature difference required for the flow direction of the resin, and It is necessary to have corresponding countermeasures for the change of wall thickness. At the moment when the molded product is released from the mold, the surface temperature of the ejected mold is uniform. A reasonable mold cooling system is necessary.
◊  The processing method
The precision requirement of the precision mold is very high, and the mold processing method is very important. The mold hole is divided according to the shape of the molded product, and the slow wire is very commonly used. Therefore, we must consider the processing method when designing
◊  A post-compensation plan
It is reasonable in the structure of the mold to facilitate the attachment of other solutions. For example, a position of the mold may not be ideal. If it is not ideal after test, a post-compensation plan is required

How to select to phone case that is fit for you

We don’t pay the insurance for our phone, but we will add some extra protection for it ， a phone case is one of the protection for your phone .So what case should we select for our smartphone ? When it comes to buying the case for our phone, we have met some problems more or less, such as “It scratches very easy” "The buttons are way to stiff when using this cases" "The color is   beautiful and it’s easy to pop on but the material is NOT durable.” Actually, most of these problems are related to the material that the phone case is made from, every material has its own advantage and disadvantage,after we know the performance of the material, we can choose a better case that is fit for you. Silicone phone case: Silicone phone case is a typical application of silicone protective cover. It’s softness is   between 35-80A Shore hardness and a slightly slippery feel . It has been popular in the market for many years. Silicone rubber, commonly known as silica gel, is a h

How does the Magfsafe achieve 15W fast charging? (The detail disassembly report of Magsafe wireless charger)

 At the press Apple launched a MagSafe magnetic wireless charger that has attracted much attention. This is also Apple's first mass-produced mobile phone wireless charger, marking the official entry of the iPhone into a new era of wireless charging. Promote the development of the wireless charging market.   The Apple MagSafe magnetic wireless charger, as its name suggests, adopts a magnetic design with a built-in magnet that can actively adsorb and align for wireless charging. This can be achieved while charging and playing, breaking the traditional wireless charging method. The main attraction is that it can wirelessly charge the iPhone 12 series at 15W, and other wireless chargers is only up to 7.5W. So as Apple's first mass-produced wireless charger, it has also made a special design, what is the inside of it? Here We will share with you the detailed disassembly of this product. 1.        Appearance of Apple MagSafe magnetic wireless charger The packaging box is a typ

Let's stop plastic waste at its sources

  Around the world, one million plastic drinking bottles are purchased every minute, while up to 5 trillion single-use plastic bags are used worldwide every year. In total, half of all plastic produced is designed to be used only once — and then thrown away.While plastic has many valuable uses, we have become addicted to single-use or disposable plastic — with severe environmental consequences.  We have seen a lot of positive action to reduce the plastic waste such as: garbage sorting,limit the use of disposable plastic products and the developing and manufacturing of the recycling. But we need to do more, we need to stop the plastic pollution at its sources   100% Biodegradable material was tested is 100% compostable and  can be completely degraded into  carbon dioxide and Oxygen in the Under natural composting and home composting conditions . As a kind of natural degradable material, biodegradable material plays a unique role in environmental protection. Its research and development
