Equipment Principle设备原理
The six-sided top press is named after its structure: six anvils advance along the six faces of a cubic synthesis cell at the same time. The cell holds the growth assembly — a high-purity graphite source, metal catalyst and diamond seed layer — and a full cycle of about seven days grows a high-quality diamond crystal from it.六面顶压机以结构命名：六个顶锤沿立方体合成腔体的六个面同步推进。腔体内部装填生长组件（高纯石墨碳源、金属触媒与金刚石籽晶层），经过约 7 天的完整周期，生长出高品质金刚石晶体。
Pre-assembled pyrophyllite/dolomite cell loaded into the press with positioning tooling to protect alignment.预组装叶蜡石 / 白云石复合腔体，通过定位工装装入压机，保护顶锤对中精度。
Six cylinders advance together to the target pressure, with automatic compensation for cell compression.六缸同步推进至目标压力，自动补偿腔体压缩量。
Heating power ramps up to bring the cell into the graphite-to-diamond conversion window.加热功率按曲线上升，将腔体带入石墨向金刚石转变的工艺窗口。
Pressure and temperature are held in closed loop while the crystal grows to target size and quality.压力与温度闭环保持，晶体在此阶段生长至目标尺寸与品质。
Ramped cooling and pressure release protect the crystal, followed by cell breakout and quality inspection.按曲线降温与卸压保护晶体，随后拆腔取样并进行质量检测。

Core Systems核心系统
Hardware and software are specified together. A weak link in any one system shows up as lost yield, so each is engineered for stability first.硬件与软件统一选型。任何一个系统的短板都会直接反映为良率损失，因此每个系统都以稳定性为第一目标。
Six synchronized cylinders act on the cube anvils simultaneously. Closed-loop servo-controlled proportional valves hold the preset pressure curve and compensate for cell deformation, keeping the pressure field symmetric through the whole growth cycle.六个油缸同步作用于六个顶锤，比例伺服闭环控制按预设压力曲线加载并自动补偿腔体形变，整个生长周期内压力场保持对称稳定。
Variable-displacement pumps with accumulator-assisted fast approach reduce installed power and wasted throttling losses. Compared with conventional stations, overall energy consumption per cycle is reduced by more than 30%.变量泵 + 蓄能器快进，降低装机功率与节流损耗。相比传统液压站，单周期综合能耗降低 30% 以上。
Indirect resistance heating with closed-loop power regulation. The controller follows the ramped heating profile of the process recipe and holds the growth window within a narrow temperature band.间接电阻加热配合功率闭环调节，控制器按工艺配方升温曲线运行，在窄温度带内稳定保持金刚石生长工艺窗口。
PLC + industrial HMI platform runs the complete cycle: assembly clamping, pressurisation, heating, holding, controlled cooling and release. Operators select a recipe and start; the system does the rest.PLC + 工业触摸屏平台完成全流程：夹紧、加压、升温、保温保压、控温降温与卸压。操作人员只需选择配方并启动，其余由系统自动完成。
Cast or wrought high-strength alloy frame with heat treatment and ultrasonic inspection. Precision anvil alignment keeps the working surfaces parallel and extends consumable life.铸造 / 锻造高强度合金机架，经热处理与超声波探伤。顶锤对中精度高，工作面对平行度稳定，延长易损件使用寿命。

FAQ常见问题
Cast frames (GY series) are produced in large moulds and cover the GY420–GY1500 range; they are the standard choice for industrial diamond mass production.
