When we receive a request for modification from our customer. After that, we analyze the requested modification, which must be done at least within the same day as the files have been received or latest the morning after if the files have been received in the afternoon. It is important to create a clear illustration of the modification (ppt file […]

When we manufacture the core and cavity inserts during the mold manufacturing, there are some dimensions that we need to manufacture with some tolerances so that it fits well in the pocket of the insert plate or cavity/core.

And this will save some work when we will fit the cavity & core, high tolerance, and good manufacturing technology will save lots of time for the moldmaster, below are some manufacturing core and cavity insert Guideline that we need to pay attention to make high quality mold.

When we make the corner radius In the manual milling machine, make a 0.2mm big step there, after hardening, we don’t have to grind on the corner when we fit […]

Weld Lines is a molding part defect that will reduce the part lifetime or even broken. Before massive production, function testing is very important,

Several years ago a customer transferred an old single cavity mold to our facility. The part was a very simple rectangular ring. It had two sub-gates, one at each end of the part on the short side of the rectangle. The material was glass-filled and made a very strong part.

We made our first sample submission and were approved for production immediately. The next day we delivered the first parts for their order. A couple of weeks after the plastic parts were delivered I […]

Polybutylene terephthalate (PBT) has advantageous combination properties such as a convenient source of raw materials, and mature polymerization process has gotten easier, low cost and easily forming and processing. Nylon, polycarbonate (PC), polyoxymethylene and modified polyphenylene oxide are five major engineering plastics.

PBT Injection Molding (Moulding):

PBT is a kind of crystalline polymer with a sharp melting point (225-235 Celsius degree). Crystallinity can reach 40%. When the temperature rises above the melting point, the liquidity of melt will become obvious. However, when changing from the molten state to the gruel state, it not only has the fast rate of cooling rate but has a fast crystalline speed.

Information about PA (Nylon) Injection Molding

Characteristic:
Nylon has tenacious and wearable, self-lubricious and smooth characteristic with non-toxic and antibiosis and high water absorbability. In addition, its tensile strength and stiffness will be sharply decreased with the moisture-absorbing. Then, the size of finished pieces changes greatly. If in the high-temperature environment for a long time, it will be resolved.

It will not soften gradually with increasing high temperature until closing to the extent of melting-point. Once reaching the proper temperature, it will flow. It is soluble in many chemicals. However, gas, lubricating oil, developer, detergent and grease have no effect on nylon.

Advantages:
It has high mechanical strength, good tenacity […]

When discussing production processes like how injection molded plastics are made, there will obviously be short-cut processes that utilize the basics of the original but are able to do it faster and for smaller quantities. There are a number of reasons that a method like this, such as Rapid Injection Molds or rapid prototype injection molding, is necessary. When a company is developing a new product, they need to create prototypes to test before they run a full-line production. Sometimes a company needs a limited supply of products that are significantly fewer than the average number in normal mass production. With situations like these, the quickness and cheapness of rapid injection molding for […]

5 axis CNC machine is used in modern industry for not only reducing the production cost, but also it saves time and increase the profit and accuracy of the job. Actually, 5 axis CNC is most useful for complex machining. We will explain it later.

The most number of CNC machine is operated under 3 axis movement which is X, Y, and Z. Those movements are mainly up-down, right-left side and front-back movement. Maximum simple machining operation is performed quite completely under these three movements. But for some special type of machining (turbine impeller) or machining, a critical surface needed some more attention. Sometimes we […]

Injection Molding Technology of Polymethyl Methacrylate (PMMA)

PMMA is commonly known as polymethyl methacrylate, acrylic and so on and its chemical name is polymethyl methacrylate. PMMA has some defects such as low surface hardness, easy to snag, low impact resistance, poor molding liquidity performance, so PMMA’s modification appears one after another such as copolymerization between methyl methacrylate and styrene and butadiene, a blend of PMMA and PC, etc. 372 PMMA is the copolymer of methyl methacrylate and styrene. If you add a small amount of nitrile rubber (about 50%) in the 372 PMMA, it will become 373 PMMA.

The fluidity of PMMA is poorer than […]
