The versatility of the injection moulding process demands much broader design considerations. Most of the design considerations will be made on the mould after setting out the product requirements.&nbsp;<\/p>\n\n\n\n<p>Some of the factors that affect the injection moulding design include: how the part will be used (singular product or for assembly), its dimensional and mechanical requirements, and its ability to withstand elements such as chemicals or pressure. Some vital tips to consider when designing for injection moulding are explored below.<\/p>\n\n\n<p><center><div id=\"i2IwM1_O-T0-69d263aa9b21a\" data-video-id=\"i2IwM1_O-T0\" class=\"ma-gdpr-youtube-wrapper\" style=\"width:100%;height:56.25%;padding-top:56.25%;\" data-new-window=\"\" data-yt-parameters=\"eyJtYXgtd2lkdGgiOiI2MDBweCJ9\"><picture class=\"ma-gdpr-youtube-thumbnail\"><source media=\"(min-width:640px)\" type=\"image\/webp\" srcset=\"\/\/xometry.pro\/wp-content\/uploads\/ma-gdpr-youtube-thumbnails\/i2IwM1_O-T0\/i2IwM1_O-T0_hq720.webp\"><source media=\"(min-width:640px)\" type=\"image\/jpeg\" srcset=\"\/\/xometry.pro\/wp-content\/uploads\/ma-gdpr-youtube-thumbnails\/i2IwM1_O-T0\/i2IwM1_O-T0_hq720.jpg\"><source media=\"(min-width:320px)\" type=\"image\/webp\" srcset=\"\/\/xometry.pro\/wp-content\/uploads\/ma-gdpr-youtube-thumbnails\/i2IwM1_O-T0\/i2IwM1_O-T0_sddefault.webp\"><source media=\"(min-width:320px)\" type=\"image\/jpeg\" srcset=\"\/\/xometry.pro\/wp-content\/uploads\/ma-gdpr-youtube-thumbnails\/i2IwM1_O-T0\/i2IwM1_O-T0_sddefault.jpg\"><source media=\"(min-width:240px)\" type=\"image\/webp\" srcset=\"\/\/xometry.pro\/wp-content\/uploads\/ma-gdpr-youtube-thumbnails\/i2IwM1_O-T0\/i2IwM1_O-T0_hqdefault.webp\"><source media=\"(min-width:240px)\" type=\"image\/jpeg\" srcset=\"\/\/xometry.pro\/wp-content\/uploads\/ma-gdpr-youtube-thumbnails\/i2IwM1_O-T0\/i2IwM1_O-T0_hqdefault.jpg\"><img decoding=\"async\" src=\"\/\/xometry.pro\/wp-content\/uploads\/ma-gdpr-youtube-thumbnails\/i2IwM1_O-T0\/i2IwM1_O-T0_mqdefault.jpg\" alt=\"\" title=\"\"><\/picture><svg class=\"ma-gdpr-youtube-button\"><use xlink:href=\"#ma-gdpr-youtube-play-button\"><\/use><\/svg><div class=\"ma-gdpr-youtube-notice\" style=\"font-size:.7em;\"><\/div><\/div><\/center><\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"h-carefully-choose-materials-suitable-for-your-design\"><strong>Carefully Choose Materials Suitable for Your Design<\/strong><\/h2>\n\n\n<p>Different injection moulding materials offer varying properties. For example, some injection moulding materials provide more dimensional stability than others. Similarly, some bond better with adhesives than others. Material design considers the following: temperature, pressure, biological and chemical interactions.&nbsp;<\/p>\n\n\n\n<p>Thermoplastic resins can be broadly classified into <a href=\"https:\/\/en.wikipedia.org\/wiki\/Crystallization_of_polymers\" target=\"_blank\" rel=\"noreferrer noopener\">amorphous and semi-crystalline<\/a>. While semi-crystalline thermoplastics offer better chemical and electrical resistance, their amorphous counterparts are much more dimensionally stable and more resistant to impact. Material selection can affect the required tolerance level or certain features, like wall thickness.<\/p>\n\n\n<div class=\"custom-table-block \" id=\"table-id-746\" >\r\n\t<div class=\"search-input-wrapper\">\r\n\t\t<svg width=\"16\" height=\"16\" viewBox=\"0 0 16 16\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\">\r\n\t\t\t<path d=\"M15.7812 13.833L12.6659 10.7177C12.5252 10.5771 12.3346 10.499 12.1347 10.499H11.6253C12.4877 9.39596 13.0002 8.00859 13.0002 6.49937C13.0002 2.90909 10.0911 0 6.50083 0C2.91056 0 0.00146484 2.90909 0.00146484 6.49937C0.00146484 10.0896 2.91056 12.9987 6.50083 12.9987C8.01006 12.9987 9.39742 12.4863 10.5004 11.6239V12.1332C10.5004 12.3332 10.5786 12.5238 10.7192 12.6644L13.8345 15.7797C14.1282 16.0734 14.6032 16.0734 14.8938 15.7797L15.778 14.8954C16.0718 14.6017 16.0718 14.1267 15.7812 13.833ZM6.50083 10.499C4.29167 10.499 2.50122 8.71165 2.50122 6.49937C2.50122 4.29021 4.28855 2.49976 6.50083 2.49976C8.70999 2.49976 10.5004 4.28708 10.5004 6.49937C10.5004 8.70852 8.71311 10.499 6.50083 10.499Z\" fill=\"#476175\"\/>\r\n\t\t<\/svg>\r\n\t\t<input type=\"search\" class=\"table-search-input\" id=\"table-search-746\" placeholder=\"Table search\">\r\n\t<\/div>\t\r\n\t<div class=\"table-wrapper\">\r\n\t\t<table style=\"border-collapse: collapse;

For lots of applications a wall thickness of 1.5-2.5 mm is sufficient, but you can also refer to recommended wall thicknesses for different materials<\/li>\n\n\n\n<li>Unlike CNC machined parts, plastic injection moulded parts benefit from a consistent wall thickness. If a part is thicker in one section than another, a sink mark will appear at that location.<\/li>\n\n\n\n<li>Non-uniform wall thicknesses also lead to warping, as these walls cool and shrink at different rates. If you require a non-uniform thickness, the change in thickness should not exceed 15% of the nominal wall thickness and should always have a smooth or tapered transition to achieve a high quality part.<\/li>\n<\/ul>\n\n\n\n<p>The following are the recommended wall thicknesses for different materials:<\/p>\n\n\n<div class=\"custom-table-block \" id=\"table-id-896\" >\r\n\t<div

However, creating a part&#8217;s design for injection moulding with vertical walls will cause the part to get stuck, particularly at the core, as the part contracts on cooling. <\/p>\n\n\n\n<p>If too much force is applied to eject the part, the risk of damaging the ejector pins and even the mould becomes very high. Design the walls of parts with a slight slant to avoid this problem. This slanting is called a draft.&nbsp;<\/p>\n\n\n\n<p>Due to the high complexity, it creates in designing, the draft is usually added at the final stages of the part design. Different surfaces require varying drafts. Textured surfaces require the most draft.

Ribs and gussets give additional strength to parts and help to eliminate cosmetic defects like warping, sink and voids. These features are essential for structural components. Therefore, it is preferable to add them to parts rather than increase the thickness of parts to increase strength.&nbsp;<\/p>\n\n\n\n<p>However, if not properly designed, this can lead to shrinkage. Shrinkage happens when the cooling rate of certain parts is much faster than others, resulting in the permanent bending of some sections. The warping can be effectively reduced by keeping the rib thickness between 50 \u2013 60% of that of the wall it is attached to.<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"h-6-add-radii-and-fillet-to-part-design\"><strong>6.

The straight-pull mould, which consists of two halves, and is the most straightforward design, is not suitable to manufacture parts with undercut features. This is due to the difficulty in machining such a mould with CNC and the tendency of the material to get stuck on ejection. <\/p>\n\n\n\n<p>Undercuts are usually created using side cores. However, side cores significantly increase tooling costs. Luckily there are some design tips to achieve the function of an undercut without using side cores. One way of doing this is by introducing a slot instead.&nbsp;<\/p>\n\n\n\n<p>This is also referred to as a pass-through core. Another way is to adjust or move the parting line of the part. When doing this, also adjust the draft angle accordingly. Moving the parting lines is most suitable for undercuts that are on the outside of the part. <\/p>\n\n\n\n<p>You can also use stripping undercuts, also referred to as bump offs. However, only use this feature when the part is flexible enough to deform and expand during ejection from the mould.<\/p>\n\n\n\n<p><strong>Also, give enough clearance<\/strong>: bump-offs must have a lead angle of 30\u00b0 to 45\u00b0 for effective ejection. All these alternatives to expensive side cores require significant redesigning of the part. When the redesign of a part is not possible due to the possibility that it may affect the functionality of the part, then you have to employ sliding side-actions and cores to deal with undercuts. <\/p>\n\n\n\n<p>These features slide in as the mould closes and slide out as it opens. The side cores must move perpendicularly and have appropriate draft angles.<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"h-8-attach-bosses-to-side-walls-or-ribs\"><strong>8.
