Company Strength:
This article is about our company's plastic Electrical Parts Mould for phone case.Home Appliances Mould for phone case is one of our company's best manufacturing molds. Our company has a strong professional design team that can produce high quality electrical molds for phone case for customers.
Product Material Selection:
First of all, the design of the plastic phone case requires a certain strength, stiffness, heat and wear resistance, and must also meet the insulation. In order to meet these requirements, ABS and PC synthetic plastics are usually used, which have good toughness (shock resistance), tightness, high mechanical strength, chemical resistance, and texture in the hand. The key points of design include the release slope, the setting of reinforcing bars, and the dimensional tolerance and accuracy of plastic parts. For example, the design of this plastic mobile phone shell, which measures 98mm x 43mm, uses stiffeners to increase strength and stiffness and to avoid forming defects caused by excessive wall thickness .
Mold Technical Requirements:
Secondly, the design of mobile phone cases follows similar principles, but pays more attention to details and technical requirements. Using PC+ABS material, the shrinkage rate should be controlled at 1.004. Technical requirements include no peaking, injection molding dissatisfaction, flow pattern, porosity, warping deformation, silver pattern, cold material, jet pattern and other defects, and meet ROSH environmental protection requirements .
Mold System Design:
The design of the mold also involves a number of systems, including pouring system, guiding and stripping mechanism, cooling system, etc. For example, in the design of mobile phone shell injection mold, the choice of gate location, the determination of process parameters, the selection and check of molding equipment are all key steps. The mold structure design includes the overall structure of the mold, gating system design, parting surface design, exhaust system design and so on. Simulation software analysis is used to evaluate the performance of the mold, including meshing, flow analysis, cooling analysis, etc .
