Thermoforming often needs fast response 吸塑成型通常重视响应速度
Plastic thermoforming may require fast vacuum response to pull heated sheet material onto the mold. 吸塑成型通常需要较快的真空响应，把加热后的片材吸附到模具表面。
Pump selection should check mold size, vacuum tank volume, cycle time and target pressure. 选型时要确认模具尺寸、真空罐容积、循环时间和目标压力。
Vacuum tank and piping matter 真空罐和管路也很关键
The pump does not work alone. Vacuum tank size, piping diameter, valves and leakage will affect the actual forming speed. 真空泵不是单独工作，真空罐大小、管径、阀门和漏气都会影响实际成型速度。
If the existing machine is slow, send photos of the pump nameplate and vacuum tank layout before replacement. 如果旧设备抽气慢，替换前建议发送泵铭牌和真空罐管路布局照片。
Common quotation information 常见询价信息
For quotation, prepare required pumping speed, machine voltage, old pump model, quantity and destination country. 询价时建议准备所需抽速、设备电压、旧泵型号、数量和目的国家。
If the required pumping speed is unknown, estimate it with the calculator and request engineer review. 如果不清楚所需抽速，可以先用选型计算器估算，再提交工程复核。
