While the primary role of the shell is to protect the internal electronics, some calculator housing manufacturers incorporate design elements that allow the casing to hold accessories, such as a pencil, as seen in the FLIP calculator.&nbsp;&nbsp;<\/p>\n\n\n\n<p>Calculator housing manufacturing is primarily done using durable plastics such as acrylonitrile butadiene styrene (ABS), high-impact polystyrene (HIPS), and polycarbonate (PC). Below are some of the roles of a calculator housing.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong><em>Protection:<\/em><\/strong> It safeguards the delicate internal electronics, like the printed circuit board (PCB) and microchips, from physical damage caused by impact and from environmental elements like water and UV. Some models have sliding covers that provide additional protection for the screen.<\/li>\n\n\n\n<li><strong><em>Organization:<\/em><\/strong> The housing is designed to have compartments for the screen, keypad, and battery. The rigid frame secures these components in place, preventing accidental damage from impact and short circuits.<\/li>\n\n\n\n<li><strong><em>Usability:<\/em><\/strong> Provides a stable base for flexible switches, allowing comfortable, responsive repeated input.<\/li>\n\n\n\n<li><strong><em>Duurzaamheid:<\/em><\/strong> The manufacturing of calculator housing is done to withstand daily wear and tear and protect the fragile internal compartments from pressure and drops.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Eisen van de klant<\/h2>\n\n\n\n<p>A calculator manufacturer was launching a new product with a unique curved design and approached First Mold to assist with the shell production. This was a unique calculator with dual screens intended for business use. They wanted a reputable company that could design precision molds for the project, and First Mold was highly recommended.<\/p>\n\n\n\n<p>First Mold\u2019s Production Manager, Bowen Huang, was delighted to give the client a physical tour of the different sections of the factory. The manufacturer openly expressed their delight and proceeded with outlining their detailed requirements for the calculator housing manufacturing.<\/p>\n\n\n\n<p>Owing to the slight curvature in the design, the client was overly concerned about balancing performance and durability while maintaining the weight of around 150 grams (0.33 pounds). The key requirements they outlined in the blueprint include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><em>Overall product weight: 125g to 150g<\/em><\/li>\n\n\n\n<li><em>Wall thickness: 1.0mm to 1.5mm<\/em><\/li>\n\n\n\n<li><em>Surface treatment: silk screen printing<\/em><\/li>\n\n\n\n<li><em>Part tolerance: \u00b10.1mm<\/em><\/li>\n\n\n\n<li><em>Assembly tolerance: \u00b10.03mm<\/em><\/li>\n\n\n\n<li><em>Mass production yield rate: \u226598%<\/em><\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Challenges and Solution<\/h2>\n\n\n\n<p>The creation of molds for products with curved surfaces is more difficult compared to products with flat surfaces. It requires high-precision, specialized machining, and labor-intensive interventions from skilled engineers. To overcome this challenge, First Mold had to rely on high-end CAD software and 5-axis CNC machining to create a steel mold for the calculator housing manufacturing.<\/p>\n\n\n\n<p>After production, the final mold surface required a considerably high degree of polishing to ensure the final product has a clean, smooth finish that is ready for silk screen printing.<\/p>\n\n\n\n<p>The primary material for this project was ABS, which typically experiences a mold shrinkage rate of 0.4% to 0.7%, depending on the grade and processing condition. First Mold engineers had to account for this contraction during the calculator housing mold production to avoid defects like warping.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Calculator Housing Manufacturing for Snap-Fit Assembly<\/h3>\n\n\n\n<p>The client wanted the upper and lower shells to feature snap-fit assembly at the edges. In addition to snap-fit assembly, the manufacturer requested the inclusion of self-taping screws to provide secondary fastening for tight, durable sealing and protection of the internal components.<\/p>\n\n\n\n<p>Snap-fits require precise molding tolerances. If the tolerances are too tight, the parts will be hard to assemble. On the other hand, if the tolerances are too loose, the connection will be weak, leading to gaps where moisture can pass through and harm the delicate internal electronic components.<\/p>\n\n\n\n<p>A major challenge with snap-fit design is the concentration of stress on the snapping arm (cantilever beam), which can cause the snap to break on assembly. To avoid this outcome and ensure the long-term durability of the product, First Mold engineers added fillets (rounded corners) to the root of the cantilever for stress distribution, leading to increased strength.<\/p>\n\n\n\n<p>Another approach of First Mold engineers to improve the snap-fit strength was tapering the cantilever beam to reduce material usage and lower peak stress. The team relied on advanced software to get the perfect fit for the calculator housing manufacturing, rather than relying on trial and error across multiple prototypes.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Designing Calculator Housing for Lightweight<\/h3>\n\n\n\n<p>Calculator housing contribute 70% to 90% of the total weight and volume. Although the client\u2019s choice of material (ABS) is usually the primary choice for consumer electronics because of its relatively lightweight nature, it was necessary to rethink the design with lightweighting in mind. Cutting down material use when manufacturing calculator housing will contribute to a lower overall weight.<\/p>\n\n\n\n<p>First Mold engineers decided to keep the wall thickness at 1.0 mm. To ensure the thin walls remain structurally functional, it was reinforced with ribs. For the best outcome, the orientation of the ribs was determined using simulation software. The ribs served more than just structural support, hence the need for better planning. Other roles played by the ribs include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong><em>Increased stiffness:<\/em><\/strong> The rib design ensured the calculator remained rigid and resisted bending. In other words, the calculator will not snap when flexed, which is great for durability.<\/li>\n\n\n\n<li><strong><em>Component mounting:<\/em><\/strong> The ribs were designed with sections where the different internal components will sit, including the button pads, circuit boards, and batteries, keeping them securely in place.<\/li>\n\n\n\n<li><strong><em>Defect prevention:<\/em><\/strong> Thin walls are prone to defects like warping, and sink marks, or visible depressions on the surface. The use of ribs allowed First Mold to create thinner, more uniform walls.<\/li>\n<\/ul>\n\n\n\n<p>The combination of thin walls and smart rib design allowed First Mold\u2019s team to deliver a calculator housing that was extremely lightweight without sacrificing structural integrity. The lightweight calculator housing design ensured that after assembly of all the components, the overall weight of the product remained below 150 grams.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Achieving a Mass Production Yield Rate \u226598%<\/h3>\n\n\n\n<p>Thoughtful gate location and venting strategy, particularly venting at the end of the flow path, were necessary to allow trapped air to escape, prevent incomplete filling, and prevent burn marks. First Mold engineers used conformal cooling channels to maintain uniform mold temperature, reducing warpage, shrinkage, and cycle time.<\/p>\n\n\n\n<p>The team of First Mold engineers designed detailed process documentation, which included design, initial setup, production, maintenance, and repair guides. This document helps the calculator housing manufacturer to optimize their production process to achieve a mass production yield of \u226598%.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why Are Curved Products Challenging to Make?<\/h2>\n\n\n\n<p>Products with curved geometries are usually more susceptible to deformation during cooling, especially if the wall thickness is not uniform. Therefore, it was important for First Mold to keep the wall thickness consistent along the curve. Inconsistency in thickness leads to differential cooling, which may cause thick areas to sink as thin areas cool too rapidly.<\/p>\n\n\n\n<p>Curved parts also have the tendency to \u2018stick\u2019 to the mold cavity more tightly compared to parts with straight walls. This makes ejection difficult with the heightened risk of damage or scratches to curved parts.<\/p>\n\n\n\n<p>The client\u2019s calculator housing design had slightly thinner walls around the screens and keypad. To prevent potential defects from differential cooling, First Mold engineers optimized the mold\u2019s cooling system using Mold Flow Analysis software to reduce internal stresses.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-the-client-gained-with-first-mold-s-solutions\">Wat de klant heeft gewonnen met de oplossingen van First Mold<\/h2>\n\n\n\n<p>The first and most important benefit the client gained from partnering with First Mold was a reduction in lead time. The client received the completed sets of production molds within 21 days, along with detailed documentation to guide process optimization.<\/p>\n\n\n\n<p>Creating a steel mold is expensive. The cost increases with design complexity. A steel mold with curved surfaces will naturally increase the tooling cost because it requires specialized tooling and labor to achieve. However, First Mold delivered the client\u2019s design within their budget by implementing design for manufacturability principles and relying on advanced technologies like 5-axis CNC machining and CAD software.<\/p>\n\n\n\n<p>Beyond delivering finished molds for the identical replication of the calculator housing design in the client\u2019s blueprint, First Mold engineers offered technical guidance on rib orientation and placement for the best structural outcome.<\/p>\n\n\n\n<p>First Mold engineers offered mentorship to the client\u2019s team on how to effectively use the machine. Even after delivery, the team continued to support the client with after-sales service to ensure the smooth operation of the mold for optimal calculator housing manufacturing.<\/p>\n\n\n\n<p>The combination of optimized production process, the implementation of design for manufacturability, and provision of maintenance and repair support ensures that the client maintains optimal production of calculator housing with minimum downtime. This will pay for the upfront investment in steel tooling over time.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-creative-calculator-shell-design\">Creative Calculator Shell Design<\/h2>\n\n\n\n<p>We denken dat sommigen van jullie die ons bedrijf volgen productontwerpers zijn.

To lower peak stress, it is important to taper the beam thickness from the root to the hook, achieving 50% less thickness at the end. This also lowers material usage and distributes stress evenly. Also, add a fillet at the base of the cantilever to reduce stress concentration.<\/p> <\/div> <\/div>\n\n\n\n<p><\/p>","protected":false},"excerpt":{"rendered":"<p>Learn how First Mold produced
