FAQs
Q1: How should one select between ABS and PC materials?
ABS presents a cost efficient solution which enables straightforward electroplating, while PC provides superior strength combined with transparent properties and exceptional thermal resistance. The selection of ABS should be made for external components while PC should be used for see through elements and parts that require protection against strong impacts.
Q2: What is the shrinkage rate of PP?
The shrinkage rate of PP ranges from 1.0% to 2.5% because different fillers and process parameters produce different results. The design process should start with an average value which designers will modify according to their needs.
Q3: Why does POM experience warping problems?
POM exhibits a maximum shrinkage rate of 2.0% to 2.5% because it contains semi crystalline material, and its properties show significant direction based variations. The establishment of precise cooling and pressure holding methods will help diminish warping problems.
Q4: Which material has the lowest unit price?
The most affordable commercial grade plastics consist of PP, PE, and PVC, which have a market value between $1.2 and $1.5 per kilogram. The complete expense assessment requires evaluation of both scrap materials and necessary processing activities.
Q5: Can recycled materials contain PCR content?
The materials can be utilized, yet their quality and stability depend on verification of the PCR ratio, supplier modification capacity, and GRS certification requirements.
Q6:Why does PEEK have a high price point?
PEEK serves as a high performance engineering plastic which maintains its structural integrity at temperatures reaching 260℃. The material possesses outstanding strength, which qualifies it for use in advanced aerospace and medical implant applications, resulting in its elevated cost.
Q7: How do you measure mold shrinkage rate?
The Material Technical Data Sheet (TDS) serves as the standard reference. The shrinkage rate for semi crystalline plastics should be set between 1.5% and 2.5% whereas the shrinkage rate for amorphous plastics should be set between 0.4% and 0.8%. Precise parts should undergo mold flow analysis.
