What to Send for a MIM RFQ Before Asking for Price\r\n  <\/nav>\r\n\r\n  <div class=\"xtmim-intro\">\r\n    <p>A useful MIM RFQ should be sent as an engineering review package, not only as a price request. Before asking for unit price, provide the 2D drawing, 3D CAD file, material requirement or application environment, critical tolerances, estimated annual volume, first order quantity, surface finish requirements, secondary operations, inspection needs, and current project stage. These inputs affect how the supplier reviews moldability, feedstock suitability, green part handling, debinding, sintering shrinkage, tooling compensation, dimensional control, post-processing, and inspection workload. If the supplier receives only a photo, part name, or rough size, the quotation may be based on assumptions that later change during DFM review. This page helps sourcing managers, project managers, and design engineers prepare a clearer MIM RFQ before tooling discussion, supplier comparison, or cost review.<\/p>\r\n  <\/div>\r\n\r\n  <figure class=\"xtmim-figure\">\r\n    <img fetchpriority=\"high\" src=\"https:\/\/xtmim.com\/wp-content\/uploads\/2026\/05\/01-mim-rfq-review-package-hero.webp\" alt=\"Engineering desk with MIM parts, 2D drawing, CAD model, and RFQ review notes for quotation preparation\" title=\"MIM RFQ Review Package\" width=\"1740\" height=\"904\" loading=\"eager\" fetchpriority=\"high\" decoding=\"async\">\r\n    <figcaption>A reliable MIM RFQ starts with drawings, CAD data, material requirements, volume, tolerances, and application background.<\/figcaption>\r\n    <div class=\"xtmim-figure-note\">The purpose of an RFQ package is to move the discussion from rough price guessing to engineering review.

It does not show complete geometry, internal features, wall thickness distribution, tolerance requirements, datum references, material grade, surface finish, inspection method, or production volume.<\/p>\r\n    <p>From a design review perspective, MIM pricing depends on more than shape. The supplier must understand whether the part can be injection molded with suitable gate placement, whether the green part can be handled without damage, whether debinding and sintering may create deformation, and whether shrinkage can be compensated through tooling. MIMA describes the MIM route as a process involving feedstock preparation, injection molding, green parts, debinding, and sintering, which is why pricing cannot be separated from process review. <a href=\"https:\/\/www.mimaweb.org\/DesignCenter\/ProcessOverviewMIM.aspx\" target=\"_blank\" rel=\"nofollow noopener\">MIMA Process Overview<\/a><\/p>\r\n\r\n    <div class=\"xtmim-table-wrap\">\r\n      <table>\r\n        <thead>\r\n          <tr>\r\n            <th>Buyer Sends Only a Photo<\/th>\r\n            <th>Buyer Sends Drawing + CAD + Requirements<\/th>\r\n          <\/tr>\r\n        <\/thead>\r\n        <tbody>\r\n          <tr>\r\n            <td>Supplier can only estimate appearance and approximate size.<\/td>\r\n            <td>Supplier can review geometry, dimensions, tolerances, and application needs.<\/td>\r\n          <\/tr>\r\n          <tr>\r\n            <td>No tolerance basis.<\/td>\r\n            <td>Critical dimensions can be reviewed.<\/td>\r\n          <\/tr>\r\n          <tr>\r\n            <td>No material confirmation.<\/td>\r\n            <td>Feedstock, sintering, and heat treatment can be discussed.<\/td>\r\n          <\/tr>\r\n          <tr>\r\n            <td>No annual volume.<\/td>\r\n            <td>Tooling and production strategy can be judged more realistically.<\/td>\r\n          <\/tr>\r\n          <tr>\r\n            <td>Higher risk of later price revision.<\/td>\r\n            <td>More stable quotation basis.<\/td>\r\n          <\/tr>\r\n          <tr>\r\n            <td>Useful only for early discussion.<\/td>\r\n            <td>Suitable for engineering review and formal quotation.<\/td>\r\n          <\/tr>\r\n        <\/tbody>\r\n      <\/table>\r\n    <\/div>\r\n\r\n    <p>In practice, a photo-only RFQ is best treated as a screening request.

This may make the part look more controlled, but it often creates confusion during RFQ review. Not every dimension affects function. If all dimensions are treated as critical, the supplier may assume extra inspection, tooling correction, or secondary machining is required.<\/p>\r\n    <p>A better RFQ separates:<\/p>\r\n    <ul>\r\n      <li>Critical-to-function dimensions<\/li>\r\n      <li>Assembly dimensions<\/li>\r\n      <li>Cosmetic dimensions<\/li>\r\n      <li>Non-critical reference dimensions<\/li>\r\n      <li>Features that may remain as-sintered<\/li>\r\n      <li>Features that may require secondary machining<\/li>\r\n    <\/ul>\r\n    <p>From a MIM process perspective, the important issue is not only whether a tolerance can be measured. The key question is whether it can be controlled through molding, debinding, sintering, support, tooling compensation, and inspection without creating unnecessary cost or yield risk.<\/p>\r\n\r\n    <h3>Inspection Requirements That Should Be Sent With the RFQ<\/h3>\r\n    <p>Send inspection requirements if they are known:<\/p>\r\n    <ul>\r\n      <li>CMM inspection requirement<\/li>\r\n      <li>First article inspection requirement<\/li>\r\n      <li>Visual inspection criteria<\/li>\r\n      <li>Surface finish requirement<\/li>\r\n      <li>Hardness requirement<\/li>\r\n      <li>Density or mechanical property requirement, if relevant<\/li>\r\n      <li>Critical dimension report<\/li>\r\n      <li>Sampling requirement<\/li>\r\n      <li>Material certificate or compliance documentation, if required by the project<\/li>\r\n    <\/ul>\r\n\r\n    <h3>Why Inspection Requirements Affect Quote Accuracy<\/h3>\r\n    <p>Inspection is not only a quality activity after production. It affects quote preparation. If the part requires CMM reports for many features, functional gauge design, 100% visual inspection, special documentation, or post-treatment verification, those requirements should be known before quotation.<\/p>\r\n    <p>If inspection requirements are not shared early, the quoted unit price may exclude work that becomes mandatory later.<\/p>\r\n  <\/section>\r\n\r\n  <section id=\"annual-volume\">\r\n    <h2>Annual Volume, First Order Quantity, and Project Stage<\/h2>\r\n    <p>Annual volume is one of the most important inputs in a MIM RFQ.

For a stronger RFQ, send both 3D CAD and 2D drawing.<\/p>\r\n    <\/details>\r\n\r\n    <details>\r\n      <summary>Why does annual volume matter for MIM pricing?<\/summary>\r\n      <p>MIM usually requires tooling and engineering setup. Annual volume affects tooling amortization, cavity strategy, material purchasing, production planning, inspection workload, and unit price discussion. A small first order may still be reasonable if the expected annual volume supports MIM production.<\/p>\r\n    <\/details>\r\n\r\n    <details>\r\n      <summary>What if the material is not confirmed yet?<\/summary>\r\n      <p>If the final material is not confirmed, send the application environment and performance requirements. For example, explain whether the part needs corrosion resistance, wear resistance, strength, hardness, magnetic response, heat resistance, or cosmetic surface quality. The supplier can then review possible MIM material directions.<\/p>\r\n    <\/details>\r\n\r\n    <details>\r\n      <summary>Should I send current CNC or casting cost information?<\/summary>\r\n      <p>If the project is being converted from CNC, casting, die casting, stamping, or another process, current cost and production issues can help the supplier understand the project goal. However, MIM pricing should still be reviewed based on geometry, material, tolerance, volume, tooling, secondary operations, and inspection requirements.<\/p>\r\n    <\/details>\r\n\r\n    <details>\r\n      <summary>What information helps avoid quotation delay?<\/summary>\r\n      <p>Send a complete RFQ package: 2D drawing, 3D CAD file, material or application requirements, critical tolerances, annual volume, first order quantity, surface finish, heat treatment, inspection needs, and project stage. Missing information often causes repeated clarification before pricing.<\/p>\r\n    <\/details>\r\n\r\n    <details>\r\n      <summary>Can I send only a minimum RFQ package for early feasibility review?<\/summary>\r\n      <p>Yes. If the project is still early, a minimum RFQ package can be enough for feasibility screening. Send the available 2D drawing, 3D CAD file, material idea, estimated quantity, and application notes. Also state which requirements are still undecided so the supplier does not treat assumptions as final quotation inputs.<\/p>\r\n    <\/details>\r\n\r\n    <details>\r\n      <summary>Can XTMIM review manufacturability before quoting?<\/summary>\r\n      <p>Yes. For MIM projects, manufacturability review should happen before formal pricing when the part has geometry, tolerance, material, or production volume risks. Send drawings, CAD files, material requirements, tolerances, surface finish, inspection needs, annual volume, and application background for review.<\/p>\r\n    <\/details>\r\n  <\/section>\r\n\r\n  <section class=\"xtmim-cta\" id=\"project-review\">\r\n    <h2>Prepare Your MIM RFQ for Engineering Review<\/h2>\r\n    <p>If you are preparing a MIM RFQ, send your 2D drawing, 3D CAD file, target material or application environment, critical tolerances, annual volume, surface finish requirements, secondary operation needs, inspection requirements, and project stage.<\/p>\r\n    <p>XTMIM can review whether your part is suitable for MIM, whether the geometry has tooling or sintering risks, whether the selected material is practical, whether critical dimensions may require secondary machining, and what information should be clarified before tooling, pilot production, or repeat production.<\/p>\r\n    <a class=\"xtmim-btn\" href=\"https:\/\/xtmim.com\/submit-drawing-for-review\/\">Submit Drawing for Review<\/a>\r\n    <a class=\"xtmim-btn\" href=\"https:\/\/xtmim.com\/contact-us\/\">Contact XTMIM<\/a>\r\n  <\/section>\r\n\r\n  <section class=\"xtmim-author\">\r\n    <h2>Author and Engineering Review<\/h2>\r\n    <p><strong>Author:<\/strong> XTMIM Engineering Team<\/p>\r\n    <p><strong>Engineering Review Focus:<\/strong> This page was prepared for sourcing managers, project managers, design engineers, and supplier quality engineers who are preparing MIM RFQ packages.
