The part materials specifically listed for these applications often encompass DC01, SPCC, Ss, and SUS grades. The mold core material is equally vital, with options such as Cr12MOV, SKD11, DC53, Skh-9, and 45# steel being standard. These materials are selected for their durability and resistance to wear, which is crucial given the high cycle counts expected. The driving motor type for the associated machinery is often a Permanent Magnet motor, contributing to energy efficiency and precise control during the stamping process.

Precision Tolerances and Mold Life Expectations

When evaluating a progressive die refrigerator blanking mold, the buyer must scrutinize the precision tolerances and the projected lifecycle of the tooling. High precision is a defining feature of these molds, with specific product tolerances ranging from ±0.02mm to ±0.05mm for the final parts. The template flatness is often specified at an even tighter tolerance of +/-0.01mm, ensuring that the alignment of the progressive stages remains accurate throughout the production run.

The durability of the mold is a primary cost driver and performance indicator. The mold life is frequently advertised as exceeding 1,000,000 cycles, with specific die life ranges extending from 500,000 to 5,000,000 shots. This longevity is achieved through advanced surface treatments such as heat treatment, nitriding, chrome plating, and Td coating. These treatments enhance the hardness and corrosion resistance of the mold components, which is particularly important for the "Trial" phase where corrosion resistance is a key attribute.

The following table outlines the key precision and lifecycle metrics observed in high-quality progressive die molds for refrigerator applications:

Buyers should verify that the supplier can consistently meet these tolerance levels, as deviations can lead to assembly issues in the final refrigerator units. The use of a three-axis NC measurement method for parts detection is a standard high-confidence fact that indicates a robust quality assurance process within the manufacturing facility.

This wide range underscores the importance of defining the specific scope of work before requesting quotes.

Several factors drive the cost of these molds. First, the customization level is a significant variable. While standard specifications exist, the market offers "Standard Specifications or Customized" options, and many suppliers provide "OEM/ODM Service" to tailor the mold to specific production lines. The "Customized" attribute is a key differentiator, allowing buyers to optimize the mold for their specific refrigerator models. Second, the material thickness and the specific stamping material (e.g., stainless steel vs. galvanized steel) impact the tooling cost, as harder materials require more durable and expensive core materials like SKD11 or DC53.

The minimum order quantity (MOQ) also plays a role in the total cost of ownership. The observed MOQ range is between 1 and 1,000 units. For a single mold purchase, the MOQ is typically 1, but for the production of parts using the mold, the volume requirements will dictate the economic viability. Additionally, the lead time, which is observed to be between 30 and 45 days (negotiable), affects the overall project timeline and inventory costs. Buyers should note that while some suppliers offer "Standard Packaging or Customized" options, the use of "Wooden Case" or "Carton" packing is standard for shipping protection.

Compliance, Certification, and Supplier Verification

In the B2B procurement of industrial tooling, verifying the compliance and certification status of the supplier is paramount. While specific certification names like ISO 9013 are mentioned in background contexts, buyers should not assume these apply to every listed product without verification. Instead, the focus should be on the supplier's ability to demonstrate adherence to quality management systems and their capacity to provide documentation for the materials and processes used.

The "Standard Specifications or Customized" attribute suggests that suppliers may operate under various industry standards. Buyers must explicitly request evidence of compliance with relevant international or national standards for mold manufacturing. The "Feature" list includes "Endurable, High Precision, Customized," which are qualitative claims that must be backed by quantitative test data. The "Parts Detection Method" using "Measurement of Three Axis NC" is a tangible quality control measure that suppliers should be able to demonstrate.

When evaluating suppliers, buyers should check for the presence of "OEM/ODM Service" and "Customized" capabilities, as these indicate a flexible and responsive manufacturing partner. The origin of the product is a critical factor; the observed data points to "Guangdong, China" and "China" as primary origins. While this provides a geographical context, buyers should verify the specific factory location and its reputation within the industry. The "Lead Time" of 30-45 days is a standard expectation, but buyers should negotiate this based on their urgency and the complexity of the order.
