https://www.lxy-silicone.cn Shenzhen Lixinyuan Technology Co., Ltd. - silicone customization insights and buying guides. zh-CN, en-US Tue, 13 Oct 2026 02:17:46 GMT https://www.lxy-silicone.cn/en/blog/silicone-kitchenware-export-compliance/ https://www.lxy-silicone.cn/en/blog/silicone-kitchenware-export-compliance/ Tue, 13 Oct 2026 00:00:00 GMT Short answer: kitchenware compliance runs three lines — material (FDA / LFGB), finished part (migration, sensory, volatiles) and destination-specific items (Prop 65, PFAS). Ask your supplier which line the report covers, and whether it tested raw material or finished goods. Industry https://www.lxy-silicone.cn/en/blog/keypad-actuation-force/ https://www.lxy-silicone.cn/en/blog/keypad-actuation-force/ Tue, 13 Oct 2026 00:00:00 GMT Short answer: feel is the combination of actuation force, travel and return curve, locked by three variables — compound hardness, key wall thickness and taper angle, and the conductive method. Put those three in the drawing before sampling and you halve the trial-and-error. Comparison https://www.lxy-silicone.cn/en/blog/o-ring-compression-ratio/ https://www.lxy-silicone.cn/en/blog/o-ring-compression-ratio/ Tue, 13 Oct 2026 00:00:00 GMT Short answer: target 15–25% squeeze for static seals and 8–15% for dynamic ones, keeping fill ratio under about 75%. Get the squeeze wrong and no compound will seal. Industry https://www.lxy-silicone.cn/en/blog/silicone-seal-failure-causes/ https://www.lxy-silicone.cn/en/blog/silicone-seal-failure-causes/ Tue, 13 Oct 2026 00:00:00 GMT Short answer: seal failure is rarely "silicone being silicone" — roughly 60% traces to selection (media and temperature), 20% to groove design, and the rest to assembly or cure. Work the list in that order and most failures are designed out before tooling. Industry https://www.lxy-silicone.cn/en/blog/silicone-phone-case-hardness/ https://www.lxy-silicone.cn/en/blog/silicone-phone-case-hardness/ Tue, 13 Oct 2026 00:00:00 GMT Short answer: mainstream silicone phone cases sit at 40–60 Shore A. Choose 40–50 A for soft touch, 55–60 A for structure and drop protection; above 70 A you are approaching hard plastic and losing the point of silicone. Comparison https://www.lxy-silicone.cn/en/blog/medical-silicone-biocompatibility/ https://www.lxy-silicone.cn/en/blog/medical-silicone-biocompatibility/ Tue, 13 Oct 2026 00:00:00 GMT Short answer: the value of medical silicone lies in grade plus validation — biocompatibility assessed under the ISO 10993 series, and the sterilization method driving compound choice. This article covers non-implant, external-contact components only. Industry https://www.lxy-silicone.cn/en/blog/lfgb-baby-silicone-en14350/ https://www.lxy-silicone.cn/en/blog/lfgb-baby-silicone-en14350/ Tue, 13 Oct 2026 00:00:00 GMT Short answer: for baby silicone shipped into the EU, LFGB covers whether the material may contact food, while EN 14350 governs the construction and safety of drinking equipment for infants. Where drinking items are involved, both apply. Comparison https://www.lxy-silicone.cn/en/blog/baby-silicone-safety-guide/ https://www.lxy-silicone.cn/en/blog/baby-silicone-safety-guide/ Tue, 13 Oct 2026 00:00:00 GMT Short answer: for baby silicone that goes in the mouth, only two things prove safety — a food-contact grade and a third-party test report for your target market. Colour, feel and price prove nothing. Comparison https://www.lxy-silicone.cn/zh/blog/silicone-kitchenware-export-compliance/ https://www.lxy-silicone.cn/zh/blog/silicone-kitchenware-export-compliance/ Tue, 13 Oct 2026 00:00:00 GMT 一句话结论：出口厨具的合规分三条线——材料（FDA / LFGB）、成品（迁移 / 感官 / 挥发性）、目的地特有条目（如加州 65、PFAS）。选厂时先问清：报告测的是原料还是成品、覆盖的是哪一条线。 行业知识 https://www.lxy-silicone.cn/zh/blog/keypad-actuation-force/ https://www.lxy-silicone.cn/zh/blog/keypad-actuation-force/ Tue, 13 Oct 2026 00:00:00 GMT 一句话结论：手感 = 按压力 × 行程 × 回弹曲线的组合，由三个变量锁定：胶料硬度、按键壁厚与锥角、导电方式。这三个参数写进图纸再打样，比后期试模来回改省一半时间。 选型对比 https://www.lxy-silicone.cn/zh/blog/o-ring-compression-ratio/ https://www.lxy-silicone.cn/zh/blog/o-ring-compression-ratio/ Tue, 13 Oct 2026 00:00:00 GMT 一句话结论：静态密封压缩率建议 15%-25%，动态密封降到 8%-15%，填充率控制在 75% 以内。压缩率定错，再好的胶料也封不住。 行业知识 https://www.lxy-silicone.cn/zh/blog/silicone-seal-failure-causes/ https://www.lxy-silicone.cn/zh/blog/silicone-seal-failure-causes/ Tue, 13 Oct 2026 00:00:00 GMT 一句话结论：密封失效很少是「硅胶不行」——六成来自选型（介质与温度）、两成来自沟槽设计、一成来自装配与硫化。按这个顺序排查，多数问题能在图纸阶段避免。 行业知识 https://www.lxy-silicone.cn/zh/blog/silicone-phone-case-hardness/ https://www.lxy-silicone.cn/zh/blog/silicone-phone-case-hardness/ Tue, 13 Oct 2026 00:00:00 GMT 一句话结论：主流硅胶手机壳落在 40-60 Shore A。要手感选 40-50 A，要挺括与防摔选 55-60 A；超过 70 A 已接近硬塑手感，失去选硅胶的意义。 选型对比 https://www.lxy-silicone.cn/zh/blog/medical-silicone-biocompatibility/ https://www.lxy-silicone.cn/zh/blog/medical-silicone-biocompatibility/ Tue, 13 Oct 2026 00:00:00 GMT 一句话结论：医用硅胶的价值在「等级 + 验证」——生物相容性按 ISO 10993 系列评估，灭菌方式决定选哪一档胶料。本文只覆盖非植入类外部接触件。 行业知识 https://www.lxy-silicone.cn/zh/blog/lfgb-baby-silicone-en14350/ https://www.lxy-silicone.cn/zh/blog/lfgb-baby-silicone-en14350/ Tue, 13 Oct 2026 00:00:00 GMT 一句话结论：出口欧盟的母婴硅胶件，LFGB 管「材料能不能接触食品」，EN 14350 管「婴幼儿饮水器具的结构与安全」。涉及饮水器具时两个都要过，缺一不可。 选型对比 https://www.lxy-silicone.cn/zh/blog/baby-silicone-safety-guide/ https://www.lxy-silicone.cn/zh/blog/baby-silicone-safety-guide/ Tue, 13 Oct 2026 00:00:00 GMT 一句话结论：婴儿入口的硅胶件只认两样东西——食品接触级牌号 + 对应市场的第三方检测报告。颜色、手感、价格都不能证明安全。 选型对比 https://www.lxy-silicone.cn/en/blog/silicone-post-curing/ https://www.lxy-silicone.cn/en/blog/silicone-post-curing/ Thu, 24 Sep 2026 00:00:00 GMT Post-curing is mandatory for peroxide-cured silicone and usually optional for platinum. What a second cure removes, what it cannot fix, which parts need it, and when it makes no difference — all sourced. Process https://www.lxy-silicone.cn/en/blog/thick-section-silicone-molding/ https://www.lxy-silicone.cn/en/blog/thick-section-silicone-molding/ Thu, 24 Sep 2026 00:00:00 GMT Silicone conducts heat poorly — on a thick part the skin seals before the core reaches cure temperature. One chain only, plus a thickness-band table, 5 DFM moves, and 4 cases where compression molding is the wrong answer. Process https://www.lxy-silicone.cn/en/blog/silicone-molding-defects/ https://www.lxy-silicone.cn/en/blog/silicone-molding-defects/ Thu, 24 Sep 2026 00:00:00 GMT Bubbles and under-cure come from parameters, shorts from charge and tooling, sticking from mold and cure state. A 30-second triage table, three bubble types, and five defects that tuning parameters will never fix. Troubleshooting https://www.lxy-silicone.cn/en/blog/platinum-vs-peroxide-cure-silicone/ https://www.lxy-silicone.cn/en/blog/platinum-vs-peroxide-cure-silicone/ Thu, 24 Sep 2026 00:00:00 GMT Short answer: parts contacting food, drinking water or the body need platinum cure; everything else defaults to peroxide. A 12-point comparison, 5 part categories, and 7 cases where you should NOT choose platinum — with every parameter traced to a cited source. Comparison https://www.lxy-silicone.cn/zh/blog/silicone-post-curing/ https://www.lxy-silicone.cn/zh/blog/silicone-post-curing/ Thu, 24 Sep 2026 00:00:00 GMT 二段硫化对过氧化物体系是必要工序，铂金体系通常可省。本文解释二段硫化去除什么、不去除什么，哪些件必须做、哪些做了也没用，均标注文献出处。 工艺技术 https://www.lxy-silicone.cn/zh/blog/thick-section-silicone-molding/ https://www.lxy-silicone.cn/zh/blog/thick-section-silicone-molding/ Thu, 24 Sep 2026 00:00:00 GMT 硅胶导热差，厚件外层已结皮时芯部可能还没到硫化温度。本文只讲这一条链，附壁厚区间难点表、5个DFM建议与不适合模压的四种情形。 工艺技术 https://www.lxy-silicone.cn/zh/blog/silicone-molding-defects/ https://www.lxy-silicone.cn/zh/blog/silicone-molding-defects/ Thu, 24 Sep 2026 00:00:00 GMT 四类缺陷归属不同环节：气泡与硫化不足查参数，缺胶查装料与模具，粘模先查固化度再查模具。附30秒速查表、三种气泡分型与欠硫对照，并写明调参解决不了的五类缺陷。 缺陷诊断 https://www.lxy-silicone.cn/zh/blog/platinum-vs-peroxide-cure-silicone/ https://www.lxy-silicone.cn/zh/blog/platinum-vs-peroxide-cure-silicone/ Thu, 24 Sep 2026 00:00:00 GMT 一句话结论：会接触食品、饮用水或人体的硅胶件选铂金硫化，其余默认按过氧化物硫化询价。12 项维度逐条对比，附 5 类件型判断与 7 条不建议选铂金的情形，全部参数标注文献出处。 选型对比 https://www.lxy-silicone.cn/en/blog/gb4806-16-2025-vs-old-standard/ https://www.lxy-silicone.cn/en/blog/gb4806-16-2025-vs-old-standard/ Mon, 21 Sep 2026 00:00:00 GMT GB 4806.16-2025 took effect on 2 September 2026, giving silicone rubber its own standalone standard. The headline change is a new "volatile matter ≤0.5 g/100g" limit. Twelve changes compared side by side, with compliance actions and a buyer’s question list. Comparison https://www.lxy-silicone.cn/en/blog/silicone-sampling-lead-time-cost/ https://www.lxy-silicone.cn/en/blog/silicone-sampling-lead-time-cost/ Mon, 21 Sep 2026 00:00:00 GMT Silicone sampling typically takes 5–7 working days, yet a 3-day quote and a 30-day quote can both be honest — the difference is the sampling method. Seven stages broken down by lead time and cost level, and which spend is worth it. Comparison https://www.lxy-silicone.cn/en/blog/silicone-supplier-evaluation-metrics/ https://www.lxy-silicone.cn/en/blog/silicone-supplier-evaluation-metrics/ Mon, 21 Sep 2026 00:00:00 GMT Stop choosing factories on "how big are they" or "do they have a good reputation". Seven criteria you can verify on the spot: dimensional pass rate, on-time delivery, sampling-to-production consistency, verifiable test reports, material traceability, tooling ownership and defect remediation — each with a benchmark and how to check it. Comparison https://www.lxy-silicone.cn/en/blog/silicone-oem-vs-odm/ https://www.lxy-silicone.cn/en/blog/silicone-oem-vs-odm/ Mon, 21 Sep 2026 00:00:00 GMT Short answer: choose OEM when you hold complete drawings and specs; choose ODM when you only have an idea and functional requirements. The difference is not quality but who designs it, who owns the IP and who pays for tooling. An 11-point comparison. Comparison https://www.lxy-silicone.cn/en/blog/silicone-vs-rubber-vs-tpu-seals/ https://www.lxy-silicone.cn/en/blog/silicone-vs-rubber-vs-tpu-seals/ Mon, 21 Sep 2026 00:00:00 GMT Short answer: silicone for wide temperature range and outdoor exposure, NBR for oil resistance, TPU for abrasion and cost. Note that silicone’s weakness is oil — choose wrong and it leaks. Comparison https://www.lxy-silicone.cn/en/blog/silicone-keypad-conductive-methods/ https://www.lxy-silicone.cn/en/blog/silicone-keypad-conductive-methods/ Mon, 21 Sep 2026 00:00:00 GMT Short answer: metal domes for a crisp tactile click, carbon pills for high volume and low cost, conductive ink for ultra-thin designs. A 10-point comparison. Comparison https://www.lxy-silicone.cn/en/blog/food-grade-silicone-vs-tpe/ https://www.lxy-silicone.cn/en/blog/food-grade-silicone-vs-tpe/ Mon, 21 Sep 2026 00:00:00 GMT Short answer: use food-grade silicone for anything touching food; TPE is viable for non-food, cost-sensitive parts. The three look nearly identical — the only reliable check is the compound grade plus third-party test reports. Comparison https://www.lxy-silicone.cn/en/blog/lsr-vs-hcr-silicone/ https://www.lxy-silicone.cn/en/blog/lsr-vs-hcr-silicone/ Mon, 21 Sep 2026 00:00:00 GMT Short answer: choose LSR for precision, transparent and high-volume parts; choose HCR for thick, heat-resistant and low-volume parts. A 12-point comparison. Comparison https://www.lxy-silicone.cn/zh/blog/gb4806-16-2025-vs-old-standard/ https://www.lxy-silicone.cn/zh/blog/gb4806-16-2025-vs-old-standard/ Mon, 21 Sep 2026 00:00:00 GMT GB 4806.16-2025 已于 2026 年 9 月 2 日实施，硅橡胶从此单独立标。最大变化是新增「挥发性物质 ≤0.5 g/100g」。12 项变化逐条对照，附合规应对与采购问询清单。 选型对比 https://www.lxy-silicone.cn/zh/blog/silicone-sampling-lead-time-cost/ https://www.lxy-silicone.cn/zh/blog/silicone-sampling-lead-time-cost/ Mon, 21 Sep 2026 00:00:00 GMT 硅胶打样通常 5-7 个工作日出样，但 3 天和 30 天的报价可能都对——差别在打样方式。7 个环节逐一拆解周期与费用量级，讲清哪些钱该花、哪些周期能压。 选型对比 https://www.lxy-silicone.cn/zh/blog/silicone-supplier-evaluation-metrics/ https://www.lxy-silicone.cn/zh/blog/silicone-supplier-evaluation-metrics/ Mon, 21 Sep 2026 00:00:00 GMT 别再用「规模大不大、口碑好不好」选厂。7 个可以当场核实的量化指标：尺寸合格率、交期达成率、打样与量产一致性、检测报告可验证性、材质追溯、模具权属、异常赔付。每项附及格线与验证方法。 选型对比 https://www.lxy-silicone.cn/zh/blog/silicone-oem-vs-odm/ https://www.lxy-silicone.cn/zh/blog/silicone-oem-vs-odm/ Mon, 21 Sep 2026 00:00:00 GMT 一句话结论：有完整图纸和规格选 OEM；只有想法和功能需求选 ODM。两者的差别不在质量，而在「设计谁出、知识产权归谁、模具谁付」。11 项维度逐条对比。 选型对比 https://www.lxy-silicone.cn/zh/blog/silicone-vs-rubber-vs-tpu-seals/ https://www.lxy-silicone.cn/zh/blog/silicone-vs-rubber-vs-tpu-seals/ Mon, 21 Sep 2026 00:00:00 GMT 一句话结论：耐高低温与户外选硅胶，耐油选丁腈橡胶，耐磨与成本优先可考虑 TPU。注意硅胶的短板正是耐油——选错了会直接漏。 选型对比 https://www.lxy-silicone.cn/zh/blog/silicone-keypad-conductive-methods/ https://www.lxy-silicone.cn/zh/blog/silicone-keypad-conductive-methods/ Mon, 21 Sep 2026 00:00:00 GMT 一句话结论：要"咔哒"手感选金属弹片，量大成本敏感选碳粒，超薄空间受限选导电油墨。10 项维度逐条对比。 选型对比 https://www.lxy-silicone.cn/zh/blog/food-grade-silicone-vs-tpe/ https://www.lxy-silicone.cn/zh/blog/food-grade-silicone-vs-tpe/ Mon, 21 Sep 2026 00:00:00 GMT 一句话结论：接触食品选食品级硅胶，不接触食品且成本敏感可考虑 TPE。三者外观几乎无法分辨，唯一可靠方式是查牌号与第三方检测报告。 选型对比 https://www.lxy-silicone.cn/zh/blog/lsr-vs-hcr-silicone/ https://www.lxy-silicone.cn/zh/blog/lsr-vs-hcr-silicone/ Mon, 21 Sep 2026 00:00:00 GMT 一句话结论：精密小件、透明件、大批量选 LSR；厚壁大件、耐高温、小批量打样选 HCR。12 项维度逐条对比。 选型对比 https://www.lxy-silicone.cn/en/blog/how-to-choose-silicone-manufacturer/ https://www.lxy-silicone.cn/en/blog/how-to-choose-silicone-manufacturer/ Thu, 20 Aug 2026 00:00:00 GMT Five key dimensions to evaluate a reliable silicone manufacturer.
