press platen with controlled cooling unit lp-s-50(20吨、80吨可选)

¨       maximum platen pressure最大压力: 50

¨       platen sizes (mm) 压台尺寸: 300x300(mm)

¨       max. opening最大开口距离: 150(mm)

¨       press size(cm)  压机尺寸: 120x70x176(cm)

¨       net weight 净重: 950kg

¨       platen heating power 加热功率: 2x5kw

¨       hydraulic motor power 液压马达功率: 4.0kw

¨       max platen temperature 最高压台温度 3000c

¨       modern designed steel cabinet with curved sliding front door and control cabinet. the front door is equipped with a large plexiglas window and the control cabinet is recessed so that it is covered by the front door when opened. the sub cabinet is built up from heavy-duty welded rectangular steel tubing and the top cabinet with aluminium profiles. a thick steel sheet table, which covers the entire sub cabinet, is supporting the four hardened and precision ground pillars as well as the hydraulic press piston. the press platens are guided on the pillars with self-lubricating bronze bearings. the top side and rear part of the press is surrounded by a heavy duty stainless steel netting which gives total safety to the operator.

现代设计的钢制外壳包含可滑动前门和控制柜,前门装有一块树脂玻璃并且控制柜凹进设计,这样前门打开时就可以盖住控制柜。控制箱的矩形结构由钢管焊接而成,上部控制箱由铝型材制成。四根硬化并精确定位的柱子和液压油缸由盖住整个控制箱的厚钢板台支撑。液压平台在带有自润滑青铜轴承的柱子上导向滑动,压片机的顶部和后部由重型不锈钢网包围为操作人员提供额外的安全防护。

¨       dual precision grounded and hard chromed press platens. the platens are built up with a sandwich construction comprising of: 压台可双精度水平调节和并镀硬铬,夹心设计的加热压台由以下部分组成:

§       the top steel plate with a thermocouple in-serted into the center part near the surface. 上层为钢板-中间靠近表面处带有插入式热电偶。

§       the intermediate thick copper plate, which contains a bank of special watt-density heater cartridges are ensuring a very even heat distribution over the entire platen surface. 中间厚层为铜质,包含一组特殊的按照功率-密度分配的加热模块,从而确保在整个压台表面非常平均的热量分布。

§       the bottom thick high-density ceramic insulation plate, which ensures minimum heat conducting to the base plate. 下层为高密度陶瓷绝缘厚板,确保只有很少的热量会传输到基板上。

¨       further the heating platens are surrounded on the sides by insulation sheets, which are covered by a stainless steel frame.

加热平台的周边由热绝缘片包围,这些热绝缘片由不锈钢支架包覆。

¨       large fully motorized hydraulic system with a fully immersed two-stage vane and gear pump system for very quiet operation. the pumps enable two-speed operation of the press with high closing speed at low pressure and low pressing speed at high pressure. the hydraulic tank has a large volume to ensure long lifetime to oil as well as the hydraulic components. the press piston is double acting to ensure that it will open in the event that the pressing compound get stuck in-between the platens.

大型全电机驱动液压系统带有全埋入两段式轮叶和齿轮泵系统从而获得非常安静的工作效果,齿轮泵在压片操作时带有双速工作模式-低压力时采用高接近速度,而当高压力持采用低压片速度。大容量的液压油储罐确保液压油和其他液压部件的长工作寿命,压片活塞采用双模操作确保压片系统在压台之间粘住时可以有效打开。

¨       two programmable digital electronic pid temperature controllers, one for each heating platen, is driving each a proportional electronic relay connected to the bank of heater cartridges. this system ensures a smooth and even heating of the platens.

针对每个热压台采用两个可编程数字式电子pid温控器,每个分别驱动连接到加热模组上的比例电子继电器。此系统确保每个热压台的平滑稳定加热。

¨       sliding knobs at the left side of the press with steel scale in mm to set the opening distance of the platens during preheating and venting. 压机左侧有滑动旋钮,上面带有精确到毫米的钢刻度,可用于设定压台在预热和排气时打开的距离。

¨       pressure regulating knob on lower front panel with pressure gauge showing the platen pressure in mt. the platens pressing pressure can be regulated infinitely from zero to its maximum rated pressure. 下面板上的压力控制旋钮带有压力表可以公吨显示压力,压台压力从零到最大值之间无级可调。

¨       optionalsingle set of pressing platens with both heating and cooling on the same platens. the two platens are built up with the same sandwich configuration as described for the standard heating platens but with additional machined zigzag channels in the middle layer for water-cooling. the press will automatically switch over to cooling when the heating cycle is completed by means of a solenoid valve, which opens up the water flow when the heating time has elapsed. thus the press has fully automatic pressing cycles as following:

(可选项)在一套压台上同时带有加热和冷却系统的压台配置。两个压台都是标准压台的夹层结构,但在中间层增加了额外的蛇型水冷通道。这样当热压过程结束后压机会通过打开螺旋水阀自动切换到冷却程序。这样压机就可以以以下的全自动方式操作:

1.  preheating with press platens near closed position在压台接近位置的预加热。

2. pressing at full preset pressure and heat. 以预设的压力和温度进行压片操作。

3.          venting = short opening followed by immediate closing of the platens. 排气 短暂打开后迅速闭合热压台。

4.  pressing at full pressure until set time has elapsed. 以全压力进行压片操作直至达到设定时间。

5.  cooling at full pressure immediately after the heat pressing cycle has elapsed. 当加热循环结束后立刻以全压力冷却。

6.  opening of press platens after cooling time has elapsed. 当冷却时间结束后自动打开压机。

¨       optionastm (iso) cooling system.where the platens are cooled with at a controlled rate of between 15ºc ± 2ºc per minute. this controlled cooling rate is required for making test sheets in type i, ii, iii and iv polyethylene and other thermoplastic resins. this method requires heating and cooling on the same platens. this controlled cooling is done with special “ramping” controllers coupled to solenoid valves on the cooling system. the ramping controllers can be set to any cooling rate between 1ºc to 20ºc but the maximum cooling rate is depending on the temperature of the cooling water supply. if the customers cooling water supply is not constant in temperature or too hot, we then recommend to install a designated water chillers.

(可选项)astm (iso)冷却系统压台冷却时以一定的受控速率冷却每分钟15ºc ± 2ºc),此控制冷却速率要求在对i, ii, iii iv 型聚乙烯和其他热塑性树脂的样片测试时采用。此方法要求采用同一压台同时带有加热和冷却功能,此控制冷却功能是通过同冷却系统的螺旋阀相联接的特殊“斜线”控制器实现的。斜线控制器可以设定为从1ºc 20ºc的任何冷却速率,但最大冷却速率取决于冷却水供应的温度,如果顾客供应的冷却水温度不稳定或太热,那么我们建议安装特定的水冷却装置。
