Plastic housing products
Injection molding shell type products have high appearance requirements, and also have certain requirements for mold manufacturing process. Let HSmold explain the difficulties in the production process of this product. In fact, the most important thing for injection shell products is to control the mold temperature and uneven mold temperature distribution, which will lead to uneven shrinkage and internal stress, resulting in greater probability of forming defects. Then there is the quality requirements of the mold. A good mold, can be more efficient production!
Hand-held vacuum cleaner injection-molded product
In modern society, vacuum cleaner is becoming a product in people’s life, and its development leads to the rise of a series of scientific and technological fields. With the continuous maturity of vacuum cleaner products and the change of people’s consumption concept, the quality, function and appearance of vacuum cleaners have become the focus of competition. The plastic part is a hand-held vacuum cleaner shell, the wall thickness of the product is uniform. Because the thickness of lip is small and prone to warping deformation, the coordination between plastic parts may have a certain impact, and it is easy to produce bubble here. For this reason, two reinforcements are added to the inner wall of the plastic parts to ensure the shape accuracy of the plastic parts. Because the plastic part is used as the surface shell of the electrical appliance, the surface requirement is smooth and there is…
Remote control product
The computer aided injection mold design of the remote controller designed by HS MOLD is designed as the die structure of one mold and two cavities in order to save the cost. Because of the different volume and size of the two mold cavities, the layout design of the pouring system should be considered comprehensively in order to facilitate the balanced filling. In order to shorten the molding cycle of plastic products, reduce warping deformation and reduce die locking force, the shape and size design of pouring system is also very important.
Car headlights Car headlights
With the development of national economy, automobile industry has become the pillar industry of the country. At present, the rapid development of automobile industry has put forward higher and higher requirements for automobile lighting. Car headlights use the most popular injection mould double injection mold. The quality of the lighting of the automobile is very important to the safety of the driving, so the laws and regulations of all the countries in the world today have strict requirements for the lighting of the automobile. The design of the lamp not only meets the safety requirements of the regulations, but also meets the requirements of some other aspects, such as the shape of the whole automobile, is beautiful and practical, meets the requirements of the aerodynamics, and makes the driver and the passenger feel comfortable and convenient. Therefore, the design technology of the lamp is changing with the development of…
Vacuum cleaner product
The part is main body for vacuum cleaner and plastic material is PP. Usually wherever the part undercut between is 0.2-0.5mm and there is no room for either lifter or slides, we will adopt use demolding. However, this under cut is as big as 10mm, so we have to use lifter on cavity and tunnel slides on the core. For the big size hole on the middle, it is 100mm deep and cooling water could not get into the block. So we have to use mold max as replacement for the cooling. Another issue comes out, use mold max as inserts on cavity, the insert line is unavoidable on cosmetic area. On one hand, machining need o be precise as possible to minimize the gap, this could be done on our high speed CNC machine. On the other hand, we suggest client to texture the area to cover the insert line….
Plastic housing for driving system of automotive
This is the plastic housing for driving system of automotive. It is usually made of aluminium, but automotive companies are now using plastic as replacement to save cost and energy. Material is Nylon+35%GF. The mechanism of the plastic injection tooling is quite complex with 11 lifters on cavity and 4 lifters on the core. Firstly, as know, the part bottom needs to be quite flat without any warp,otherwise the oil may leak. Secondly, there are 16 locating holes around the parts, and each of them contracts towards different direction irregularly and the position of the holes move during the molding process. In this case, we have to make all holes as inserts and note down the molding parameter. After trial, we measure the actual position and make new inserts. This process has to be repeated until the holes fit with the assembly metal parts. The big hole on the middle…
How to fix Splay mark on PP plastic injection molded part
Splay mark, is also called as Splash Mark or Silver Streak.It is a cosmetic defect that occurs in plastic injection molding process, when silver or white streaks appear on the surface of the molded part. Sometimes Splay can be quite difficult to determine, as the appearance is very similar to other injection molding defects, such as surface scratches, scuffs, flow lines, delamination from contamination, and flaking (also known as cold slugs). Why there is Splay? There are many possible reasons for the appearance of splay mark, molding process, the mold itself, the machine, or the material. Material The most common cause of splay is material moisture. It is easy to identify that. The moisture splay does not occur in the same place every time, or in some cases the splay is all over the part. In this case, use dry material, review material drying process, review material storage for contamination issues Molding process Too much heat can have an appearance similar to moisture splay. The…
Injection Molded PP Plastic Part Warp – How To Fix It
PP is one of the most commonly seen soft plastics on the market. It is applied to a variety of industries including packaging,automotive industry, like Step Pads, and other household products. Though for its wide use, PP is meanwhile is a very flexible, soft material with a relatively low melting point. Because of all these factorers, PP plastic molded part is most liable to get warped under heat,which becomes an annoying headache in daily production. .How to solve the warp on PP plastic parts? According to HS’s over 20 years of practical experience, there are basiclly 3 ways. Improve designIn product design, use reinforced ribs with appropriate size wherever possible. For large area of surface, design it as micro-arc shape with equal wall thickness to reduce the internal stress. Improve processing parameterMost warp in plastic injection molded part is caused by uneven stress. There are only 4 primary plastic processing variables…
