Industrial Design


We directly submit the customer’s product concept and requirements concept to our engineers. The first class international design concept based on engineers experiences. It’s creative to the traditional concept, and it is the philosophy of the break the normal procedure. All are cycles of creation and destruction, thinking of the collision, wisdom is docking, novel and creative ideas.


Creativity is a breakthrough, product appearance, marketing model, market mechanism, function and other aspects of the breakthrough.


Creativity is the result of comprehensive application of logical thinking, image thinking, reverse thinking, divergent thinking, systematic thinking, fuzzy thinking and intuition, inspiration and other cognitive methods. Pay attention to intuition and inspiration. Many ideas come from intuition and inspiration.


Originality (Creativity)


Creativity is mysterious. From ancient to modern times, scholars have different understanding of the creative. They defined are different.  RobertJ.Sternberg believes that creativity is the ability to produce works, these works not only novel (that is, the originality is not to be expected), and appropriate (that is consistent with the purposes for goal given limit).


Architectural scholar Cudici (JohnKurdich) believes that creativity is a struggle, seeking and liberating our inner.


Mr. Lai Shengchuan said, “creativity is the process of seeing new possibilities and combining these possibilities into a work.” These definitions show that creativity consists of two main aspects: “conception”, “execution”, “seeking” and “liberation”, which show the creative work of the two aspects at a deeper level. Mr. Lai Shengchuan called these two parts “two mysteries” of creativity, independent and interrelated, through two steps – the emergence of desire and the way to express it.


Product creativity (Product Creativity)


Product creativity refers to anything that can be provided to the market, used and consumed by people, and can meet certain needs of the people, including tangible goods, intangible services, organizations, ideas, or their combinations. Products can generally be divided into three levels, namely, core products, formal products, extended products.


The core product refers to the overall product available to buyers directly benefit and utility; form product refers to the product on the market of physical appearance, including product quality, features, style, trademarks and packaging products; extension refers to the overall product to provide a series of additional benefits to customers, including transportation, installation and maintenance to ensure to consumers in the field of consumption benefits.



Mechanical Design



Wall Thickness


The size of the plastic material of the basic design code of wall thickness depends on the product to bear force, whether as other parts of the support, to undertake a number of columns, the number of protruding part as well as the selection of plastic materials and. In general, the wall thickness design of thermoplastics should be based on 4mm. From an economic point of view, too thick products not only increase material costs, extend production cycle, increase production costs.


From the point of view of product design, the possibility of increasing porosity caused by too thick products greatly weakens the rigidity and strength of the products.


Mold temperature higher than the melting temperature of plastic material is low, when the plastic material into the mold from the mouth just pumping, due to lower temperature of mold, the mold surface will form a layer of crystal layer, about 0.2MM, can cause the compound space is very small.


It would need injection pressure is very large, it may cause to fill, there are some thin wall injection molding technology is designed.


The ideal wall thickness distribution is undoubtedly the uniform thickness of the section in any place, but in order to meet the functional requirements, the wall thickness change is always inevitable.


In this case, the transition from a thick rubber to a thin rubber should be as smooth as possible. So suddenly the wall thickness transition will lead to unstable size and surface caused by different cooling rate and produce turbulence.


A bar


The role of stiffeners is an integral part of the plastic components. Stiffeners increase the rigidity and strength of the products without increasing the cross-sectional area of the products, especially for some plastic products which are often subjected to pressure, torsion and bending.


In addition, the stiffener acts as an inner channel filling cavity and plays a significant role in helping the plastic flow into the support section of the component.


The design of reinforcement is generally placed on the non contact surface of plastic products with the extension direction, should follow the product of maximum stress and maximum displacement direction of stiffeners position, also subject to some production considerations such as die cavity filling, shrink and release etc.




  1. pillar is used to assemble the product, separate the object and support the other parts.


  1. hollow pillars can be used to insert parts, tighten screws and so on.




A, stop and reverse stop is closely related with the use of exergy. The function of the orifice is opposite to that of the stop, and the reverse orifice prevents the outer deformation of the B shell and prevents the A shell from shrinking inward.


B and the check are on the shell that is at the end of the mother.


C, the design of the anti stop opening to the attention of the male buckle from unilateral 8.0MM exergy of at least 6.0MM, because to deformation.




Design of buckle is generally cannot do without the so-called method of cantilever; cantilever, is based on the characteristics of plastic deformation of the flexure itself, after the return of the original shape of elastic recovery.




the buckle provides a kind of assembly method which is not only simple and fast, but also has low cost and high reliability. It is easy to buckle, assemble and disassemble, and make full use of the idea of assembly by designers.


Because of a combination of partial buckle position at the same time the production of finished molding, the assembly does not need to cooperate with other parts such as screws, etc.



The locked meson assembly process, buckle position is also very simple, generally only need an insert action, without rotation or assembly before the product positioning work, as long as the two sides need a combination of buttons a buckle can cooperate with each other.




buckle device weakness is a combination of two parts of buckle, hook shaped flange part and protruding part after many repeated use easy to deform because of fatigue effect, buckle bottom connection parts of products breaking, breaking after buckling is difficult to repair.


This situation is more common in brittle the incorporation of fiber or plastic materials.


Because of the simultaneous molding of the buckle and the product, the damage of the buckle is the damage of the product.


The remedy method is that the buckle device is designed as multiple buckles and shared at the same time, so that the whole device can not operate because of the damage of the individual buckle, thereby increasing its service life.


Another weakness buckle device is fastened size tolerance requirements are very strict, inverted position too easy to form buckling damage, on the contrary, the inverted position is too difficult to control the assembly position or combination part appeared loose phenomenon.





Commonly used metal materials:


  1. cold rolled steel plate, cold rolling is at room temperature, the steel plate further rolled thin thickness of the target plate SPCD, calendering, forming quality, advertising box, learning shell, etc.


  1. galvanized steel sheet is coated with zinc on the surface of cold rolled plate. Fingerprint resistant corrosion resistance, excellent processability, and maintain common grades of cold rolled plate, SECC SECD SECE advantages, from the perspective of cost, SGCC and SECC, will be sent to the factory processing parts electroplating, plating time and save transportation costs.



  1. stainless steel, anti atmospheric, acid, alkali, salt and other media corrosion of stainless acid resistant steel collectively. To achieve the corrosion effect of chromium (Cr) amount of not less than 13% in addition to exergy nickel (Ni) and molybdenum (Mo) to increase the effect.


Because of the variety and content of alloys, there are many kinds. Stainless steel features, good corrosion resistance, good brightness, high strength, a certain degree of elasticity. Common stainless SUS301 exergy spring steel, SUS302 SUS30



Reinforcement of die casting, the design requirements of reinforced rib, rib role is to increase the strength and rigidity of die castings, reduce the casting shrinkage deformation, avoid the workpiece ejection from the mold deformation, as the melt filling auxiliary loop, melt flow path.


We should pay attention to the following requirements: exergy
The stiffeners of die castings should be less than the thickness of the ribs
