PVC strap mould\u00a0Base Q&A<\/span><\/p><\/h1><\/div>

I. Informazioni di base sul prodotto<\/strong><\/span><\/p>\n<\/div>

Q1: What are the differences between Hard Chrome and Teflon surface treatment?<\/span><\/strong><\/p>\n

A1: Hard chrome plating is durable and long-lasting, standard for export molds.
\nTeflon coating is super smooth for easy demolding with less release agent, but needs regular recoating later.<\/p>\n<\/div>

Q2: What is the disadvantage of hard chrome plating mold?<\/span><\/strong><\/p>\n

A2:It requires even spraying of release agent on cavity. Uneven coating will cause product sticking, bubbles and surface defects.<\/p>\n<\/div>

Q3: When is Teflon coating recommended?<\/span><\/strong><\/p>\n

A3: It is suitable for high-demand surface products. But you need local Teflon factory to support later renovation.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

II. Settori e materiali applicabili<\/strong><\/span><\/p>\n<\/div>

Q4: Why need customer provide shoe samples?<\/span><\/strong><\/p>\n

A4: Size fitting standard varies in different countries. Full or adjacent size samples are required for accurate size grading.<\/p>\n<\/div>

Q5:Is it allowed to skip sizes for size reference?<\/span><\/strong><\/p>\n

A5: No. Skipping sizes cannot confirm size difference rules, which will lead to unqualified size matching.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

III. Conoscenze specifiche sulle modalit\u00e0 di alimentazione (nuovo capitolo ampliato)<\/strong><\/span><\/p>\n<\/div>

Q6: Why do flip flop straps have deformation or wrong length?<\/span><\/strong><\/p>\n

A6: The product is soft and high temperature after demolding. Forcible pulling will cause elongation and deformation.<\/p>\n<\/div>

Q7: Are the drawing dimensions the actual mold size?<\/span><\/strong><\/p>\n

A7: No. Drawings show finished size after shrinkage. We will add shrinkage rate during mold processing.<\/p>\n<\/div>

Q8: How to control production sizes with one multi-size mold?<\/span><\/strong><\/p>\n

A8: Install screws at nail head position. Lock the screws to close feeding ports, only produce required sizes.<\/p>\n<\/div>

Q9: Do I need to buy a mold base for the mold?<\/span><\/strong><\/p>\n

A9: Yes. Horizontal machine must use mold base for fixing. One machine matches one mold base for long-term use.<\/p>\n<\/div>

Q10: What is the difference between rubber and PVC material?<\/span><\/strong><\/p>\n

A10: Rubber is softer, more comfortable and high-grade with higher cost. PVC is cost-effective for mass production.<\/p>\n<\/div>

Q11: Any different post-processing for rubber and PVC straps?<\/span><\/strong><\/p>\n

A11: PVC needs no manual trimming. Rubber requires manual edge removal and flash cutting.<\/p>\n<\/div>

Q12: What machines are compatible with rubber sole molds?<\/span><\/strong><\/p>\n

A12: It fits both traditional and automatic rubber hydraulic pressing machines, wide application.<\/p>\n<\/div><\/div><\/div><\/div><\/div>
