How to Confirm Production Scheduling and Track Progress in Real Time

Schedule Locking and Milestone Notification Mechanism

• System-driven production planning: Once the contract is signed, the order is immediately entered into the ERP system. The production planning department automatically generates the Production Schedule based on the principles of "delivery priority and balanced capacity," and confirms the lead time to the customer within 24 hours.
• Progress briefings: Customers do not need to be on-site. A dedicated sales contact provides regular production progress updates covering key milestones: raw material receipt, rough machining completion, precision machining (such as laser cladding), final assembly, and factory acceptance testing.
• Special witnessing options: For critical processes such as non-destructive testing and pressure testing, customers may request remote video witnessing or on-site inspection. The system records full-process data in the background to ensure transparent and verifiable progress.

Execution standard: Any process that falls behind the planned milestone triggers an automatic system alert. The production department then issues catch-up measures to ensure the final delivery date is not affected.

How Bulk Orders Are Scheduled and Production Capacity Guaranteed

Dedicated Flow Lines and Inventory Buffer Strategy

• Flow-line production: For large-volume orders of identical mining equipment cylinder models, Wantong adopts a "dedicated line, batch flow" model to minimize changeover frequency and maximize scale production efficiency.
• Backward scheduling: The total order volume is broken down into daily output targets with a "daily completion, daily settlement" tracking system, ensuring production plans are granular to the day and responsibilities are assigned to individuals, avoiding the common pitfall of slow starts and rushed finishes.
• Safety stock buffers: Safety stock of blanks and semi-finished parts is maintained for standard cylinder specifications, effectively hedging against raw material supply fluctuations and ensuring continuous production for large batch orders.

Capacity assurance: With full in-house capability across all production processes, Wantong reduces reliance on outsourced work. Even for centralized procurement orders worth tens of millions of yuan, internal resource scheduling ensures sufficient capacity release.

How Order Changes (Rush, Reschedule, Add-ons) Are Coordinated

Change Review and Closed-Loop Control Process

• Formal request submission: When a customer requests a change — earlier delivery, production suspension, or quantity increase — a written application (email or official letter) must be submitted to the sales contact.
• Cross-functional review: The sales department leads a joint review involving engineering, production, procurement, and quality teams. Key assessment points include whether technical drawings are frozen, whether raw materials are available, whether current capacity is fully utilized, and the impact of the change on the original delivery date.
• Closed-loop confirmation: The review result is communicated to the customer in writing by the sales department. If cost or delivery adjustments are involved, a Supplementary Agreement must be signed by both parties before the change takes effect. Without written confirmation, the factory maintains the original production plan to prevent disruptions caused by verbal instructions.

Risk control principle: Orders that have already entered precision machining or final assembly stages are generally not eligible for cancellation or major process changes, in order to avoid asset losses.

Can Urgent Orders Be Expedited? What Is the Shortest Lead Time

Rush-Order Response and Lead-Time Compression Solutions

• Green channel: Wantong operates an "urgent order response mechanism" for emergency scenarios such as mine rescue operations or equipment downtime repairs. A level-one response can be activated, bypassing the normal queue and prioritizing machine tool resources.
• Lead-time definition: For standard custom products, lead time can be shortened by 30%–50% by compressing non-critical path activities, such as running procurement and pre-treatment in parallel. For highly complex custom products with special structures or materials, the minimum lead time depends on supply chain verification due to raw material procurement cycles.
• Supply chain coordination: Core suppliers of seals and special steels are required to activate their own rush-order mode simultaneously to guarantee material kit completeness.

Preconditions: Expedited orders incur a corresponding rush production fee, and technical parameters must be finalized upfront with no mid-process modifications accepted.

Do Customers Need to Provide Installation Plans to Align Delivery

Mine-Side Coordination and Just-in-Time Delivery

• Information alignment: It is recommended that customers share the Mine Installation Progress Schedule and Underground Commissioning Plan after signing the purchase contract, especially the key time nodes related to longwall face installation.
• Inventory optimization: Based on the customer's installation timeline, the factory implements just-in-time delivery. This avoids blind shipments when the mine site is not ready to receive goods, which could otherwise lead to cylinder corrosion, seal aging, or loss during outdoor storage.
• Phased delivery: For long-cycle longwall projects, phased delivery terms are supported. Goods are delivered in 3–4 batches aligned with face advancement progress, reducing the customer's capital commitment and warehouse management burden.

Best practice: Customers should notify the factory of the specific underground transportation plan 7 days in advance, so that final cleaning, protective packaging, and logistics vehicle scheduling can be arranged accordingly.

How Is On-Time Delivery Rate Guaranteed

Full-Chain Planning and Performance Assessment System

• Four-level plan decomposition: A "year → month → week → day" four-level planning management system decomposes delivery targets down to teams and individuals, with clear owners and deadlines for each stage.
• Process control: A weekly sales-production balance meeting reviews the previous week's plan achievement rate and resolves bottlenecks such as equipment failures or labor shortages. Orders deviating from plan trigger light-up alerts and mandatory intervention.
• Buffer allocation: Reasonable buffer times are set before and after critical processes such as heat treatment and plating to absorb fluctuations from abnormal events. A semi-finished "reservoir" is maintained to handle sudden order increases.
• Performance linkage: On-time delivery rate is included in the KPI assessment of production and sales departments and directly linked to performance-based pay, driving all departments to prioritize delivery commitments.

Track record: The average on-time delivery rate over the past three years has exceeded 98%, demonstrating stable delivery capability for large-scale centralized procurement orders from major energy enterprises.
