<p dir="auto">模具润滑不仅影响脱模质量，更直接决定模具寿命。选对润滑产品，模具寿命可延长30%以上。</p>
<hr />
<h3>一、导柱润滑油（最常用）</h3>
<p dir="auto"><strong>用途：</strong> 模具导柱/导套、滑块导轨润滑</p>
<p dir="auto"><strong>要求：</strong></p>
<ul>
<li>粘附性好（不易滴落）</li>
<li>耐高温（150C-200C及以上）</li>
<li>防锈防腐</li>
</ul>
<p dir="auto"><strong>推荐品类：</strong></p>
<ul>
<li>高温链条油（粘度220-460）</li>
<li>复合锂基脂（NLGI 1-2号）</li>
<li>二硫化钼润滑脂：高压工况首选</li>
</ul>
<p dir="auto"><strong>使用频次：</strong> 每2-4周补充一次</p>
<hr />
<h3>二、脱模剂/脱模膏</h3>
<p dir="auto"><strong>用途：</strong> 型腔表面喷涂帮助制品脱模</p>
<p dir="auto"><strong>两种主流类型：</strong></p>

<p dir="auto"><strong>品牌：</strong> Marbocote、MOLYKOTE、深圳中润、东莞富强</p>
<p dir="auto"><strong>误区：</strong> 不要用机油代替脱模剂！</p>
<hr />
<h3>三、模具高温润滑脂</h3>
<p dir="auto"><strong>用途：</strong> 顶针板、斜顶、滑块等高摩擦面</p>
<p dir="auto"><strong>关键指标：</strong></p>
<ul>
<li>滴点需大于260C</li>
<li>基础油粘度100C时大于等于100cSt</li>
<li>增稠剂：复合锂/复合铝/聚脲</li>
</ul>
<p dir="auto"><strong>极端工况：</strong> PFPE全氟聚醚润滑脂<br />
<strong>一般高温：</strong> 复合锂基脂+二硫化钼</p>
<hr />
