Analysis of the whole production process of iPad case: 18 processes from mould development to quality inspection

In the digital accessories market, the iPad case as a popular product, its production process contains a number of complex processes. Understanding these processes not only allows us to understand how the quality of the product is forged, but also to engage in the mobile phone case wholesale, custom mobile phone cases and other related industries will be helpful, after all, some of the process principles are similar.

Mould development and design

Demand research: According to different iPad models, analyse the market demand, which is the same as the custom-made mobile phone cases need to understand the requirements of the customer's phone case model. Define the function and design direction of the case, for example, whether it is designed for anti-drop, and whether the appearance is minimalist or cartoon style.

Design drawings: professional designers based on the results of the research to draw detailed drawings to determine the size of the protective cover, the location of the keys, the size of the opening and other details, this step is the blueprint for the entire production.

Mould making: According to the drawings, adopt high quality steel to make the mould to ensure the precision of the mould. The good or bad of the mould directly affects the forming effect of the protective cover, just like the mobile phone case wholesale, the quality of the mobile phone case produced by a good mould is more popular.

Material Preparation

Material selection: According to the positioning of the case, choose the right material, such as silicone for soft and anti-drop, plastic for light texture. This is similar to the selection of materials by customers for customised mobile phone cases.

Raw material procurement: Procurement of raw materials in line with quality standards to ensure the stability of supply to meet the needs of large-scale production, the wholesale business of mobile phone cases, a stable supply of raw materials is the basis for guaranteeing the volume of shipments.

Material Inspection: Strict inspection of the purchased raw materials to check whether there are impurities, whether the physical properties are up to standard, etc. Only qualified materials can enter the production process.

Production Processing Stage

Injection moulding: Put the raw materials into the injection moulding machine, inject them into the mould cavity under high temperature and high pressure, and then mould them after cooling to form the shape of the protective cover initially.

De-burr treatment: Remove the burrs on the edges of the protective cover caused by injection moulding, so as to make the appearance of the product smoother.

Printing and Painting: Printing patterns and text through silkscreen, pad printing and other processes, or painting, to enhance the aesthetics of the protective cover, like adding personalised elements to the phone case.

Lamination process: If there is a multi-layer structure, the lamination operation is carried out to ensure that the layers are closely integrated.

Key assembly: Install the key components on the protective case to ensure that the keys feel and function properly.

Hole opening process: Precisely open the holes for the camera, ports and other parts of the case to ensure accurate fit with the iPad model.

Secondary processing: Sanding, polishing, and other secondary processing of some products to enhance the texture.

Quality Inspection

Appearance Inspection: Manually inspect the appearance of the case to see if there are scratches, colour differences, and defects in the printing of the pattern.

Size Measurement: We use professional gauges to measure the size of the case to ensure that it matches the iPad model precisely, just as mobile phone cases should be adapted to different mobile phone case models.

Functionality test: Test the flexibility of the buttons, the accuracy of the holes, the firmness of the fit and other functions are normal.

Durability test: Simulate daily use scenarios and conduct drop and bend tests to check the durability of the case, especially for the anti-drop function.

Pre-packaging sampling: random sampling again before packaging to ensure that the shipping product quality is qualified, which is crucial to the quality assurance of the wholesale cases.
