Pin Point Gate Plastic Injection Molding

Used mainly for thin walled products with a frequency-lawyer-an injection of at least 3-4 times per minute, or a maximum cycle time 15-20 seconds a mold cavity with pin point gate. Material which is the injection into the cavity directly derived from the nozzle G, where the drop in temperature as well as barriers pengalirannya very small, so the size of the gate can be made small. Table 3.1 above can be used as guidance in determining the diameter of the gate d. -injection material in the cavity before reaching the runners will pass through the channel C first. The longer the runner channel, the temperature of the material tip of the flow would be decreased, so it will be difficult to pass through the narrow gate. Pouch runner dimasudkan D material to trap and hold the channel tip, so the material that will go through the gate, pretty good. Regarding the size of the gate, but is determined by the weight of products such as Table 3.1 above, is also affected by the condition and the condition of the bend cross-section and length of the runner. As a measure of onset, can be taken from table 3.1 size plus 20%. After ditrial if showing signs of too little gate as described in advance, gate be enlarged as necessary

Ribs and Gussets

When designing ribs and gussets, it is important to follow the proportional thickness guidelines shown in Figures 29 and 30. If the rib or gusset is too thick in relationship to the part wall, sinks, voids, warpage, weld lines (all resulting in high amounts of molded-in stress), longer cycle times can be expected. The location of ribs and gussets also can affect mold design for the part. Keep gate location in mind when designing ribs or gussets. For more information on gate location, see page 66. Ribs well-positioned in the line of flow, as well as gussets, can improve part filling by acting as internal runners. Poorly placed or ill-designed ribs and gussets can cause poor filling of the mold and can result in burn marks on the finished part. These problems generally occur in isolated ribs or gussets where entrapment of air becomes a venting problem. Note: It is further recommended that the rib thickness at the intersection of the nominal wall not exceed one-half of the nominal wall in HIGHLY COSMETIC areas. For example, in Figure 29, the dimension of the rib at the intersection of the nominal wall should not exceed one-half of the nominal wall. Experience shows that violation of this rule significantly increases the risk of rib read-through (localized gloss gradient difference). 

Product and Mold Design

SMAW Welding

Welding is the process of switching between two or more metals by using heat energy. Metal around the welds / connections, will experience a rapid thermal cycling which leads to complex changes, metallurgy, deformation and thermal stresses. It is very closely related to the strength, weld defects, and so forth which in general will have a fatal effect on the safety of welded construction. Welding process involves heating and cooling, in general, the microstructure of the metal depends on the speed of the cooling of the initial phase formation temperature up to room temperature. Because of this structural change on its own mechanical properties owned are also changing. Basically the weld area consists of three parts, namely the weld metal (weld metal), heat affected area is often referred to as the Heat Affected Zone (HAZ), and a metal stem that is not affected by heat. Weld metal region is part of the metal during welding melts and then freezes. Regional influence of heat or base metal HAZ is adjacent to the weld metal during welding thermal cycles of heating and rapid cooling. Unaffected parent metal heat is part of the basic metal welding where the heat and the temperature did not cause changes in the structure and properties. In addition there are three parts of other parts of the area which limits the area between the weld metal and HAZ are called the limit of welding. All events during cooling of the welding process is similar to cooling in the foundry difference is: 1. Cooling in the welding speed is higher 2. In the weld heat source moves straight 3. Thawing and freezing in the welding occurs continuously 4. freezing of weld metal from the metal wall of the parent which can be equated with the walls of the casting mold, only in the welding, the weld metal should be the one with the parent metal, while the foundry should be otherwise.
