This occurs by <strong>aspirating<\/strong> the material. Therefore, it is important to make the molds to the <strong>correct tolerance<\/strong>, as this will affect the dimensions of the final product.<\/p>\n\n<p class=\"wp-block-paragraph\">In order to maintain dimensional repeatability, <strong>stability of<\/strong> the molds is essential, as the molds heat up during the thermoforming process.<\/p>\n\n<p class=\"wp-block-paragraph\">Molds for thermoforming are usually cheaper and simpler to produce than tools for other technologies. The cost of the <strong>mold<\/strong>also <strong>depends<\/strong>on the size and complexity of the product, but is usually about <strong>50-90% lower<\/strong> than <a target=\"_blank\" rel=\"noreferrer noopener\" href=\"https:\/\/plastipol.pl\/en\/technologies\/injection-molding\/\">in injection molding<\/a> technology.<\/p>\n\n<p class=\"wp-block-paragraph\">Type of mold used for thermoforming plastics<br\/>depends on the required <strong>accuracy<\/strong>, <strong>demand<\/strong>, <strong>size<\/strong> and <strong>complexity<\/strong> of the product.<\/p>\n\n<p class=\"wp-block-paragraph\">Thermoforming molds have openings that are used to drain air.

We mostly use them for <strong>small<\/strong> and <strong>medium production runs<\/strong>. The implementation consists of two stages:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>Produce a pre-mold (e.g., from MDF)<\/li>\n\n\n\n<li>Making a &#8220;hoof&#8221; and then casting a resin mold.

It is an alternative to resin molds. Plastics can also be 3D printed, although this is mainly applicable to prototypes.<\/p>\n\n<h4 class=\"wp-block-heading\">Aluminum<\/h4>\n\n<p class=\"wp-block-paragraph\"><strong>Aluminum molds are the most commonly used by us<\/strong>. They are used for medium and large production runs.

The molds consist of many components. <strong>Tooling has a high price, and production is very efficient<\/strong>, which positively affects the price of manufactured parts.<\/p>\n\n<h3 class=\"wp-block-heading\"><strong>Production methods<\/strong><\/h3>\n\n<p class=\"wp-block-paragraph\">Molds for production in thermoforming technology are not as complicated as, for example, in injection molding technology. The most commonly used production methods:  <\/p>\n\n<h4 class=\"wp-block-heading\">CNC machining<\/h4>\n\n<p class=\"wp-block-paragraph\">The most common way to produce thermoforming molds is <strong>CNC machining<\/strong>. This is the default manufacturing method. During production, <strong>vents<\/strong> can be easily added to remove air, and the minimal porosity of the mold allows for high precision detailing.  <\/p>\n\n<p class=\"wp-block-paragraph\">CNC machining involves the proper<strong> removal of material<\/strong> from a larger piece\/block.  <\/p>\n\n<p class=\"wp-block-paragraph\"><strong>Aluminum<\/strong> can be processed, as well as <strong>wood<\/strong> or <strong>plastic<\/strong>.<\/p>\n\n<h4 class=\"wp-block-heading\">Casting<\/h4>\n\n<p class=\"wp-block-paragraph\">Casting involves the creation of a suitable mold (hoof) into which the material is poured, which then solidifies.<\/p>\n\n<p class=\"wp-block-paragraph\"><strong>Resin<\/strong> can be cast, and the process is described in the paragraph on resin molds.<\/p>\n\n<p class=\"wp-block-paragraph\">The cast <strong>aluminum<\/strong> is melted and molded into the shape of a mold.  <\/p>\n\t\t<div data-elementor-type=\"section\" data-elementor-id=\"7749\" class=\"elementor elementor-7749 elementor-4580\" data-elementor-post-type=\"elementor_library\">\n\t\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-59d27b72 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"59d27b72\" data-element_type=\"section\" data-settings=\"{&quot;jet_parallax_layout_list&quot;:[]}\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-419deac6\" data-id=\"419deac6\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<section class=\"elementor-section elementor-inner-section elementor-element elementor-element-477c78e3 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"477c78e3\" data-element_type=\"section\" data-settings=\"{&quot;jet_parallax_layout_list&quot;:[],&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-inner-column elementor-element elementor-element-35bd17e3\" data-id=\"35bd17e3\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-24a64469 elementor-widget elementor-widget-heading\" data-id=\"24a64469\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h6 class=\"elementor-heading-title elementor-size-default\">Don't wait!<\/h6>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-667e48dc elementor-widget elementor-widget-text-editor\" data-id=\"667e48dc\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><span style=\"font-weight: 400;\">Tailor the technology to your needs to reduce plastic production costs.<\/span><\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-22171ce elementor-align-left elementor-widget__width-auto elementor-widget elementor-widget-button\" data-id=\"22171ce\" data-element_type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<div class=\"elementor-button-wrapper\">\n\t\t\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-md\" href=\"#footer\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t\t\t\t<span class=\"elementor-button-text\">Consult your project<\/span>\n\t\t\t\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-inner-column elementor-element elementor-element-725b156d elementor-hidden-mobile\" data-id=\"725b156d\" data-element_type=\"column\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t<div class=\"elementor-widget-wrap\">\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t\n\n<h4 class=\"wp-block-heading\">3D Printing<\/h4>\n\n<p class=\"wp-block-paragraph\">3D printing is the least commonly used method for producing thermoforming molds. It has its uses practically exclusively for <strong>prototypes<\/strong>.<\/p>\n\n<h2 class=\"wp-block-heading\">Molds for thermoforming &#8211; breakdown<\/h2>\n\n<p class=\"wp-block-paragraph\">Choosing the right material and mold making method depends on several factors. The most important of these is <strong>production volume<\/strong>.<\/p>\n\n<h3 class=\"wp-block-heading\">Prototype molds<\/h3>\n\n<p class=\"wp-block-paragraph\">When producing prototypes, the most important thing is to minimize costs so that, if necessary, several different molds are made before a satisfactory result is obtained. For this reason, we most often use molds of machined MDF.<\/p>\n\n<h3 class=\"wp-block-heading\">Molds for mass production<\/h3>\n\n<p class=\"wp-block-paragraph\">For mass production, we usually use molds made of <strong>machined aluminum<\/strong>. Depending on the volume of production and the complexity of the product, we may also use a different material (e.g. resin, plastic, MDF), as well as the production method (e.g. cast aluminum).<\/p>\n\n<h3 class=\"wp-block-heading\">Molds for mass production<\/h3>\n\n<p class=\"wp-block-paragraph\">In thermoforming technology, mass production refers to thin-walled parts, such as blisters. For such production, all tooling made of different <strong>steel<\/strong> alloys is used to ensure the <strong>highest efficiency<\/strong>.<\/p>\n\n<h2 class=\"wp-block-heading\">Thermoforming molds &#8211; prices<\/h2>\n\n<p class=\"wp-block-paragraph\">The cost of molds depends on many factors, including. size, required dimensional tolerance, shape, etc. Below are the forks that apply to most &#8220;standard&#8221; implementations:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>The cost of <strong>wooden molds<\/strong> usually ranges from <strong>several hundred<\/strong> to <strong>1.5-2 thousand<\/strong> zlotys net.<\/li>\n\n\n\n<li><strong>Resin molds<\/strong> are usually a net cost of <strong>2-4 thousand <\/strong>zlotys.<\/li>\n\n\n\n<li><strong>Aluminum molds<\/strong>, is the cost of the order of <strong>4-10 thousand <\/strong>zlotys net.<\/li>\n\n\n\n<li><strong>Steel<\/strong> tooling for mass production is a cost <strong>starting at tens of thousands of zlotys<\/strong>.<\/li>\n<\/ul>\n\n<h2 class=\"wp-block-heading\">Making a prototype before mass production.<\/h2>\n\n<p class=\"wp-block-paragraph\">To make a prototype, it is necessary to make a mold beforehand. However, there is a way (often used by us) that allows you to make a prototype at a lower cost.<\/p>\n\n<p class=\"wp-block-paragraph\">The target material for mass production is usually aluminum. Often we suggest making a wooden mold (MDF) beforehand, the cost of which is an order of magnitude lower. We work on such <strong>a prototype form<\/strong> until we get a satisfactory result. The next stage is already making <strong>the target mold, for efficient mass production<\/strong>.<\/p>\n\n<p class=\"wp-block-paragraph\">Another solution is to first make a prototype mold and then use it to make a &#8220;backhoe&#8221; from which the target mold will be cast. Note, however, that there are casting shrinkages that affect the dimensions. For this reason, it is rarely used by us.<\/p>\n\n<h2 class=\"wp-block-heading\">Summary<\/h2>\n\n<p class=\"wp-block-paragraph\"><strong>Thermoforming<\/strong> is a technology that is widely used in industry. Inherent in this are the <strong>molds<\/strong>, the making of which is necessary to start production.<\/p>\n\n<p class=\"wp-block-paragraph\">The <strong>cost of the molds is relatively low<\/strong>, compared to other technologies, which lowers the entry threshold for launching production.<\/p>\n\n<p class=\"wp-block-paragraph\">There are both a <strong>variety of materials<\/strong> and <strong>production methods for thermoforming molds<\/strong>. Depending on the individual project, we make the appropriate choice based on factors such as implementation cost, production volume, efficiency, required accuracy, etc.<\/p>\n\n<p class=\"wp-block-paragraph\"><strong>Thinking about, manufacturing with thermoforming technology? <\/strong><a href=\"https:\/\/plastipol.pl\/en\/contact\/\" target=\"_blank\" rel=\"noreferrer noopener\">\n  <strong>Consult your project<\/strong>\n<\/a><strong> with us, and we will advise you on the best material to make a mold for your project.<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Thermoforming is a technology for producing open products with uniform wall thickness, such as lids, containers, housings, but also blisters or trays.
