This unique characteristics of the LSR fluid, unlike the high consistency rubber or compression-molded silicone, which easily flows into long, thin-wall sections and down narrow mold cavi-ties without excess flash. However, this benefits only if your foundry control the whole supply chain-meter-ing, tooling, curing and part inspection-under one roof.\n            <\/p>\n        <\/header>\n\n        <div class=\"lsr-grid\">\n            \n            <article class=\"lsr-card\">\n                <h3 class=\"lsr-h3-title\">\n                    <span class=\"lsr-step-num\">01<\/span>\n                    <span class=\"lsr-title-text\">Challenge 1: Tight Tolerances Demand Specialized LSR Equipment<\/span>\n                <\/h3>\n                <p class=\"lsr-card-desc\">\n                    Standard squeeze and injection moulding machines are not able to hold the 0.025mm tolerances that precision LSR parts demand. Liquid Silicone Rubber (50,000-500,000 mPas fluid viscosity) is so low viscous, that any imbalance in the metering system or temperature deviation greater than 2 C will create flash, short shots or dimensional drift. We operate dedicated 150T LSR presses with a specific 2 components metering unit and static mixer set to 1:1 ratio accuracy. Our mold shop construct cold runner system to prevent material wastage and to achieve cavity-to-cavity repeatability across 64 mold cavities.\n                <\/p>\n            <\/article>\n\n            <article class=\"lsr-card\">\n                <h3 class=\"lsr-h3-title\">\n                    <span class=\"lsr-step-num\">02<\/span>\n                    <span class=\"lsr-title-text\">Challenge 2: Material Selection Confusion Leads to Wrong Process Decisions<\/span>\n                <\/h3>\n                <p class=\"lsr-card-desc\">\n                    How often do engineers call out HCR (high consistency rubber) in processes that require the installation of LSR- or that could receive a cycle reduction from 5 min to 60 sec? Or compression mold for parts tolerances of 0.05mm or less-which compression was incapable of due to bias problems? For free DFM analysis in 2-3 business days, Engelhardt includes the ideal material, taking into account your Shore A (5-80A for LSR), volume, tolerance class, and sterilization specification. Use the decision matrix detailed in Section 3 for a starting point.\n                <\/p>\n            <\/article>\n\n            <article class=\"lsr-card\">\n                <h3 class=\"lsr-h3-title\">\n                    <span class=\"lsr-step-num\">03<\/span>\n                    <span class=\"lsr-title-text\">Challenge 3: Quality Uncertainty with Overseas Silicone Rubber Suppliers<\/span>\n                <\/h3>\n                <p class=\"lsr-card-desc\">\n                    Chinese sourcing of silicone rubber parts-initial consistency concerns. This is a legitimate concern for manufacturers that do not incorporate process controls. Engelhardt carries both ISO 9001:2015 and IATF 16949-the automotive quality standard that mandates documented PPAP, SPC monitoring, and complete batch traceability. Every rubber incoming lot has a Mooney Viscometer and Moving Die Rheometer tested before it even arrives to the press.

With Engelhardt prototype runs from 100 pieces on single-cavity tools at the $8K-$15K range that fully transfer the investment of the mold to the customer, you get to retain ownership and we maintain it for free during the first year. As quantities increase, we build production molds with amortization schedules through to short breakeven within 12-18 months on typical production volumes.\n                <\/p>\n            <\/article>\n\n        <\/div>\n    <\/div>\n<\/section>\n<\/div><\/div><\/div>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-stackable-columns alignfull stk-block-columns stk-block stk-5c6b0d6\" data-block-id=\"5c6b0d6\"><style>.stk-5c6b0d6 {margin-bottom:0px !important;}<\/style><div class=\"stk-row stk-inner-blocks stk-block-content stk-content-align stk-5c6b0d6-column alignfull\">\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-b7621ba\" data-v=\"4\" data-block-id=\"b7621ba\"><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-b7621ba-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-b7621ba-inner-blocks\">\n<style>\n\/* =========================================\n   Scope: #lsr-equipment-premium\n   Design: Ultra-Flat, Industrial Editorial, Strict Grid\n   Constraint: 5-column row, zero irregular whitespace\n   ========================================= *\/\n\n#lsr-equipment-premium {\n    position: relative;\n    width: 100% !important;\n    padding: 40px 0 !important;\n    background-color: #ffffff !important;\n    box-sizing: border-box !important;\n}\n\n#lsr-equipment-premium * {\n    box-sizing: border-box !important;\n}\n\n#lsr-equipment-premium .lsr-container {\n    max-width: 1280px !important;\n    margin: 0 auto !important;\n    padding: 0 24px !important;\n}\n\n\/* --- 1.

Liquid silicone rubber injection molding uses a cold, liquid, low viscosity two-part platinum catalyzed compound that is pumped and metered into heated molds (150200C). Takes 30-90seconds and can achieve 0.025mm tolerances. HCR is hot solid material, preformed, and loaded manually. Uses a peroxide or platinum cure, cycle time of 2-5 minutes and 0.08mm tolerances possible. Use LSR for high volume precision parts (>10K per year). Use HCR for lower volume, extremely hard parts (>80Shore A), or when tooling costs need reduced.<\/p>\n                                                    <\/div>\n                    <\/div>\n                <\/article>\n\n                <article class=\"lsr-faq-item\">\n                    <button class=\"lsr-faq-trigger\" aria-expanded=\"false\" aria-controls=\"faq-ans-3\">\n                        <h3 class=\"lsr-faq-h3\">Can silicone rubber be injection molded?<\/h3>\n                        <span class=\"lsr-faq-icon\"><\/span>\n                    <\/button>\n                    <div id=\"faq-ans-3\" class=\"lsr-faq-answer-panel\" role=\"region\">\n                        <div class=\"lsr-faq-answer-inner\">\n                            <p class=\"lsr-faq-text\">Whether you can do this with silicone? Yes &#8211; Liquid silicone rubber (LSR) injection molding. A two part platinum catalyzed system is injected into heated moulds of 150-200 degrees celsius. A flashless, high precision process with fully automated potential. Unlike the regular thermoplastic injection process (hot material in a cold mould), the injecting of cold material into a heated one results in essential crosslinking, permanent elasticity which is stable from -60 to +200 \u00b0Celsius.
