Die Casting Mold Design Guideline

In order to be able to think in the same way within SinereTech, and to be able to use dimensions that are suitable for all applications we have created the following guidelines. Those guidelines will be used by the calculation engineers as well as a base for our designers in case of any die casting plastic mold project.
  1. Injection gate and overall layout.
    1. Generally, the injection gate will be placed along the longest side of the part and the injection gate cylinder will be on the closest distance to that side (runner will normally not go around the cavity like a banana).
    2. If sliders are used or if other factors may influence the placement of the injection gate or runner ask the customer what they recommend in each case. Agree with a solution before the mold design. Then the general layout will be suitable for almost all die casting mold.

  2. Distance between the cavity edges and the insert edges.
    1. For normal cases, except for die casting molds with bigger sliders or “deep” parts, use the distance 60-80mm. The upper limit is used for “bigger” parts and the lower limit is for smaller parts.
    2. For die casting tool with bigger sliders the distance can be up to 90-100mm, especially when it concerns the two sides to right and left from the slider side.
    3. For really deep parts the distance may be bigger than 100mm, but then we should ask the customer for advice if suitable the customers die casting machine.
    4. For really small parts the minimum distance of 50mm is used.
    5. The distance for the side towards the injection cylinder is the same as for the other sides, but about 10-15mm on top of that.
    6. In case we would like to optimize this distances. This can preferably be used for this type of die casting tools
  3. Distance between cavities.
    1. Generally, a distance of 60-80mm is used for most cases.
    2. For really small parts the distance of a minimum 45-50mm is used.
    3. For really deep parts the distance is generally bigger than 80mm, but then we should ask the customer for advice if the die casting mold size is fitting to the customer’s machine.
    4. For cases when the runner is between the cavities the distance will be increased with 30-40mm on top of what the distance would have been without the runner (see a, b and c).
  4. Distance between the edge of the insert and the edge of the mold base.
    1. Generally (for normal cases) the rule is to use the same distance as what is used for Injection Mold China (as long as the part do not require big sliders). That includes bigger parts, deeper parts and parts requiring smaller sliders. That means a distance of 60-90mm is OK for most molds.
    2. For molds with big hydraulic sliders, there is a need to increase the distance with 50-200mm on top of the normal distance (more than what would have been needed for injection moulding). However, for those cases, we should ask the customer for approval. One question is also how asymmetrical the mold can be in case a big slider is only used on the right or left side of the mould.
  5. The thickness of A/B plates and inserts.
  6. The thickness for both the inserts and A/B plates are mainly controlled by the part projected area. As a rule of thumb thicknesses specified in below table will be used when designing die casting molds. The projected areas are specified in cm2. For big projected areas or deep moulds it is recommended to ask the customer for approval. There may be formulas to use in case those dimensions will be optimized
Plastic injection mold is the primary process for manufacturing plastic parts. Although the tooling of plastic injection mold is expensive, the cost per part is very low. Today most of the companies are looking for mold manufacturer China suppliers to reduce the mold cost.

How To Be A Successful Plastic Mold Company in China

Always I got auction notices in private email inbox and staring at the photographs of the shops that are going out of business, you were wondering: What does it turn to be a perfect plastic mold china or plastic injection molding manufacturer?plastic mold company
Many of the auction photographs reveal some of the best state-of-the-art equipment, such as high-speed and precision CNC machine and manufacture tools, the use life of injection molding machines is less than five years old, vision quality systems(projector), CMMs, everything it gets- or so it looks – to make for a successful mold business. Yet, there it all is – listed for auction. So what does it cause? Evidently, it takes more than the latest, greatest, state-of-the-art equipment. After all, anyone with money can buy the best equipment. one China injection mold expert, informal survey get out a few answers: Money, Money…….. one-China plastic mold company’s owner said, “Money- and that’s also my final answer.” of course, that is True, if a China plastic mold china spend a lot of money to buy the best machine and for day by day maintenance expenses.
But except for the money, it also causes a business plan. China plastic mold companies make money by making the right business with the right customers – preferable customers who pay their bills for the China plastic injection mold companies. Above all, China plastic injection mold companies that run under the best machine, which causes them to have the ability to finish the job well. That let one plastic injection mold maker respond, “No financial sense.” Plastic Injection Mold and molding manufacturer owners have become a much more business-savvy lot over the past decades, and that’s a good phenomenon, maybe there is another answer besides money “professional, talented toolmaker” because only the professional toolmaker can maximize the equipment’s capabilities. That’s what China plastic injection mold maker replied besides “lots of money.” Toolmaker is the heart of any China plastic injection mold manufacturer. The molds can get shipped out from the back door are only as good as the people on the production floor.
Maybe next time if I get an auction flyer for a plastic injection mold or metal manufacturer shop in my e-mail inbox, and I think about the reason, using all this advanced equipment, did this plastic injection run out of normal business, I’ll never forget what one china mold gave as his answer to what it causes to be successful-” a love of injection mold making.” Perhaps in addition to money, business savvy, having the right customers for the right job, financial know-how, and state-of-the-art machine, the bottom line for success is as simple as a love of mold making or plastic injection molding.

Insert Molding (Moulding), Plastic Injection Molding

SINCERE TECH offers Insert Molding Services as an add-on to the plastic injection molding service.  There is one direct difference between the two processes; the plastic injection molding process only uses plastic material in order to create a product.  On the other hand, the Insert Molding process includes other types of plastic and/or metals in order to create a more advanced product. There are thousands of uses for Insert Molding manufacturing.

The Insert Molding Process

The Insert Molding process starts off by either inserting the metal inserts before the custom injection molding process, or they can be inserted during the custom injection molding process.  If the inserts are chosen to be inserted during the plastic injection molding process, an Insert Moulding process operator or a robotic arm will load them.  If chosen to insert the metal inserts after the plastic injection molding operation, the same robotic arm or Insert Molding process operator will load them after the plastic injection molding process is complete. Usually, Insert Molding takes place after the custom mold manufacturer China process. This procedure ideally reduces insertion costs, which can save our customers substantial costs on custom insert molding projects. If you want to know more knowledge about insert moulding, please go to what is insert molding page to take a look.
Regarding the Insert Molding process, there can be some very nice advantages when a robotic arm is handling parts.  When it comes to removing the molded parts and getting them ready for more processes, a multiple-axis robot can do that faster and more accurate than a human.  After the molded part is created and removed from the mold, the robot grips the part and moves it to either a location to be held or onto a system to be inspected.  The manufacturing equipment’s general layout and the kind of product being created are the determining factors in making this choice.
In order to assure a high level of quality for many parts that go through Insert Molding, robots can have vision systems mounted on them.  These vision systems inspect parts faster than a human, as well as know exactly what the metal component’s placement accuracy is.
Several industries thrive upon the products created through the Insert Molding process.  Actually, there are so many products created through this type of custom injection molding process, to buy inset molding from Injection Mold China company, that will save super cost since the low labor cost in China.  Here is a list of the industries these products belong to, and there is a list of the products that are created through this type of custom injection molding:

How To Make Precision Insert Pins

I am trying to find out how large manufacturing companies grind precision core pins. As a plastic mold maker, I am aware of the manual methods using a surface grinder and Harig type spin fixture and am also familiar with the Ded-Tru machine.
However, these methods are exceedingly slow, albeit quite precise. There just has to be some kind of OD grinder, tool grinder, centerless grinder or special CNC tool grinder that can grind complex mold core pins accurately and with an excellent finish.
Plastic Mold
But in today, normally the mold maker is not making any pins or insert pins by themselves, you can find some precision components company who specializes in making high precision components, like insert pins and some small inserts, you only need to send them the 3D, 2D drawing and mark the tolerance for each dimension, then they will do the rest quickly and accurately.
But for some other mold components, you may have to do this by yourself.
Another common material for various plastic mold maker  is a beryllium copper alloy also called Mold Max. It has excellent heat transfer qualities, can be polished and is also pre-hardened. All this combines to make it the material of choice for things such as core pins.
However, is beryllium copper/Mold Max safe?
In my experience is depending on which area of mold components you are using for? I made 64 cavities moldswhich the parts have some small ribs, the customer was a requirement with MoldMax for better cooling, as you know sixth four core inserts made by Mold Max, that is not cheap, but after the second time of mold trial the small ribs start to break, not only one or two but around 10 inserts had broken done, base on my experience on this material, for some small ribs it is not good option to use Beryllium copper, if some deep ribs but have much more space, then that will be better option to use this material, because you will get good cooling to save cycle time.
This covers the topic in detail and my conclusion is that it is basically depending on the part design, Is you have a plastic mold project that may need this service, you are welcome to send me your drawing, we will suggest you some good option for you to make choices this could be safer for your project.
