What is soft tool and hard tool?Soft tool is the tool made of pre-harden steel, it is an economic solution for a small volume production. It has advantages of low cost and fast turn around, but pre-harden steel is a lower grades steel that process lower hardness and wear resistance, so the soft tool can only stand molding cycles no more than 500k shots, it's also difficult to maintain tight tolera...

What is mold flow? Mold flow analysis is widely employed in mold making industry, utilizing data simulation software, the injection molding process can be simulated and presented on the computer, you can improve part design or mold design base on the out put results. Moldflow, Moldex3D are very popular mold flow analysis software used by many mold makers. Advantages of mold flow analysis Mold fl...

Injection molding is one of the most important processing methods to produce plastic parts. Plastic injection molding techniques have been used and developed for a long time. Look around you, the case of your laptop, the case of intelligent cell phone, water filters, food containers, wash machines and quite a few components in your car... yes, we are living in a world that are full with plastic pa...

After a new injection mold is construction is finished, the mold maker need to set up the injection mold to do test or molding plastics. Setting an injection mold is more than loading and fixing the mold to injection machine, there are many other important things to do after you clamp the injection molds. This article will give you a comprehensive explain of how to setup an injection mold, and the...

A good mold flow analysis has lots of benefits, although it is time consuming, the cost is much lower than the cost of trials during nights and days on a production injection molding machine. The difficulty is not to produce colored pictures but to explain to the customers the different results, some customers have enough knowledge to understand some others no. In 90% of cases, I work before the i...

Plastic enclosures are plastic cases or housings manufactured by injection molding process. Usually a popular consumer product with great enclosure design catch people's eye immediately without promoting how good the function are, a very success example is Apple product, success industrial design contribute a lot to the success of Apple in worldwide.How to make a custom plastic enclosure? First yo...

Guiding system of injection mold works as guides to ensure precise mechanic movements. Generally the standard mold base all have guiding design, like guide pins between cavity side and core side, mold designers can just choose the proper mold base. Typical mold guiding system include, guiding between A/B plates, guiding for stripper plates, guiding for runner plates, guiding for ejector pins. All ...

CompressionThe process of compression molding may be simply described by reference like two-piece mold provides a cavity in the shape of the desired molded article. The mold is heated, and an appropriate amount of molding material is loaded into the lower half of the mold. The two parts of the mold are brought together under pressure. The compound, softened by heat, is thereby welded into a conti...

Scientific Molding to me is a bit different than having a whole lot of data studies. To me, and to many of my peers, scientific molding is an disciplined elimination of multiple variables, which yields an range of conditions/settings/protocol/things that you must do. This will yields the highest volume of acceptable parts with the least amount of cost. I.E., when you do this, and you do that - the...

You can get a larger shot size out of a hydraulic injection molding machine. There are times when you are pushing the injection capacity of the injection unit that hydraulic machines are a better choice than all-electric injection molding machines. However, if the job is within the range of the injection unit and specified properly, the electric machines outperform hydraulic for repeatability and ...

Two types of injection-compression used for thin walled high aspect ratio parts. The first uses a moving side core or secondary cylinder that leaves the cavity spaced and upon injection clamps forward to compress the part stress free. This usually requires a specific capability of the press. The second method sometimes referred to as coining closes the mold under reduced clamp pressure and the cav...
