Insert into the mold forming means of the different materials prepared after the inserts into the resin, the melt solidified bonding material and inserts, made of molded construction method of integration products.
1, ease of molding of resin, metal bending rigidity, strength and heat resistance of each combination of added complexity and sophistication can be made of solid metal to plastic integrated products.
2, in particular the use of insulating resin and a combination of conductive metal, moldings made of electrical products to meet the basic function.
3, multiple insert the pre-forming composition, makes the product portfolio after the unit works whenever necessary.
4, insert product entirely limited to the metal, there are cloth, paper, wire, plastic, glass, wood, line rings of class, and other electrical components.
5, the rigid moldings, rubber seals on the flexural plate moldings through injection molding substrate made of integrated products, eliminating the need for sealing rings of the complex arrangement of work, so after the combination of process automation easier.
6, because the material is molten metal inserts in the joints, and pressed into shape Comparatively, metal inserts can be designed more narrow gap, forming composite products more reliable. .
7, select the appropriate resin and molding conditions, that is easy to Bian-shaped broken for products (such as glass, coil, electrical parts, etc.) can also be sealed by resin fixed.
8, select the appropriate mold structure, insert materials can also be completely enclosed in resin.
9, vertical injection molding machine with mechanical hand, insert the entire product series combination of devices, insert molding can achieve a large-scale automated production.
10, insert molding, after a deal to core hole can also be made into a hollow cavity Bands products.
Automatic insert molding systems design choices Note
1, the metal insert molding mold shrinkage prone to heterogeneity, should be done in advance important parts of the shape, dimensional accuracy of the limit test.
2, injection of metal embedded in the process of easy deformation and displacement, should take full account of the structure and easy to maintain the metal mold insert mold the shape of the design. The inserts can not change the shape of the product, prior testing is indispensable.
3 the arrangement of metal inserts separate occasions using conveyor, the metal inserts and the inserts and vibration between the ball contacts the surface of inserts will slightly damage, affect product quality. In advance to confirm the scope of permissible limits of its quality.
4, metal inserts shall be determined in advance because the stamping process caused by serrated warpage, material thickness difference, difference in diameter, the thickness of deposited gold due to poor processing. On the basis of the automated installation options for the design and mold construction design.
5, mold gate location methods, molding cycle, mold construction restricting the predictability of the matter, as far as possible to resolve or there is a corresponding improvement measures.
6, should recognize the need for preheating metal inserts or dried. Purpose is to ensure product quality and shape stability.
7, mold set up various testing devices in the mold to heat, force, vibration under the influence of environmental conditions to ensure stability by forming action, shall determine whether to use.
8, in order to avoid the metal insert, molded fine film deposited on the mold cavity, if necessary, can be assembled to air blowing device.
9, due to the high price of equipment investment system, to fully consider the possibility of using the former to ensure the running of the production equipment. Special occasions by machine, it is necessary to ensure that no form of updated products in the past few years the premise of continuous production.
10, adopt a common plane when the occasion required to confirm many varieties of small batch insert the number of combinations of production. If the whole mass production can not be guaranteed when the daily, each a product of the fixed assets of the recovery is difficult. In this case, to be replaced after a certain portion of the devices within the species adapted to update the requirements.
11, injection machine, molds, automation equipment and effective combinations and how to function in a short time, is to determine the automatic insert molding systems critical.
12, decided to insert molding rate, the cost of production and molding conditions of metal goods, precision inserts, insert shapes, molds are beneficial to insert molding and molding products and technologies and other factors shape decisions clever.
