Project Overview

Customer Background

A Precision Forging Manufacturer Looking for a Reliable Custom Supplier

The customer is a precision forging manufacturer in Pakistan producing hot and cold forging molds and metal stamping components. The company was looking for a reliable supplier capable of producing customized punches and ejector pins in small quantities.

For the initial trial order, the customer required only five pieces for each item. Rather than placing a large-volume order before verifying quality, the customer wanted to evaluate the products first and establish a reliable supplier relationship for future orders.

The Challenge

Small-Batch Customization Without Compromising Quality

The customer was actively looking for a long-term supplier but faced several practical challenges when sourcing customized mold components internationally.

• Small Trial Quantities: Each item required only five pieces for the initial trial order, which limited the customer’s choice of qualified suppliers.
• Cross-Border Payment Requirements: Due to the customer’s local payment procedures in Pakistan, suppliers needed to accept RMB corporate-to-corporate transfers to a mainland China account.
• Need for Production Transparency: The customer also wanted clear production updates, process information, and QC evidence during manufacturing to reduce uncertainty when working with a new overseas supplier.

Engineering Review

Drawing and Requirement Review

The customer provided PDF drawings for the customized punches and ejector pins. HTX reviewed the dimensional requirements and production specifications before confirming the order.

Because the parts included internal grooves requiring EDM machining, dimensional requirements were carefully reviewed before production. This step ensured that the EDM-machined features could be manufactured within the specified tolerances.

Manufacturing Process

Precision Machining and EDM Groove Processing

The manufacturing process followed these key stages:

Material Preparation → Lathe Machining → Centerless Grinding → Heat Treatment → Punch Machining → EDM Groove Processing → Surface Grinding → Polishing → Final Inspection

The main manufacturing challenge was the EDM machining of internal grooves on partial punch components. These features required careful control of groove dimensions and positioning to ensure that the finished parts matched the customer’s drawings.

HTX has accumulated extensive experience in EDM groove processing for high-speed steel punch components, allowing these customized features to be manufactured while maintaining the required dimensional accuracy.

Quality Inspection

Dimensional Accuracy Verified Against Customer Drawings

All finished components were inspected against the customer-approved drawings. Key dimensions, including the EDM-machined groove features, were checked before shipment to ensure that the final parts met the specified requirements.

The customer received the required quality documentation and inspection evidence together with the shipment.

Packaging & Delivery

Transparent Communication and Secure Packaging

The finished components were packed using net bags, stretch film, foam padding, and cartons to protect the precision parts during handling and transportation.

As the customer had their own freight forwarder in China, the shipment was prepared for direct pickup from the HTX factory.

During production, HTX proactively shared workshop production videos and informed the customer in advance about the EDM processing schedule and the impact of the Qingming Festival holiday. The exact completion date was communicated throughout the process so that the customer could coordinate the pickup with their forwarder.

Project Results

Before: Customer was looking for a qualified supplier for small-batch custom components
After: HTX became a qualified supplier for customized punches and ejector pins

Before: Only 5 pcs were required for each item for the initial trial
After: HTX supported the customer’s small-batch trial order

Before: Uncertainty about quality from a new supplier
After: Product quality met the customer’s expectations

Before: Production progress needed close monitoring
After: Regular production updates and QC evidence were provided

Before: Supplier relationship had not yet been established
After: Customer placed two repeat orders after the trial order

The initial 35-piece trial order successfully led to two repeat orders, and HTX has since become a stable, qualified supplier for the customer.

Customer Feedback

After receiving the shipment, the customer confirmed that the products had arrived safely and expressed satisfaction with the previous order’s quality. The customer subsequently placed additional orders with HTX.

“Last time the quality was good; we were satisfied. Please make sure of the sizes 👍”

Engineering Insights

Insight 1 — Small Trial Orders Can Build Long-Term Supplier Relationships

For customized mold components, a small initial order gives overseas customers an opportunity to verify dimensional accuracy and product quality before committing to larger or repeat orders.

Insight 2 — EDM Groove Processing Requires Early Dimension Review

For punches with internal grooves, key groove dimensions should be reviewed against the customer’s CAD drawings before production. Allowing sufficient processing time for EDM machining helps reduce the risk of dimensional issues during final inspection.

Insight 3 — Production Transparency Builds Trust

For first-time overseas orders, sharing production progress, explaining potential delays, and providing QC evidence can reduce uncertainty and make it easier for customers to coordinate their own logistics.

From Trial Order to Long-Term Partnership

What started as a small trial order of 35 customized punches and ejector pins developed into a long-term supplier relationship. After the initial order met the customer’s expectations, the customer placed two repeat orders. HTX is now registered as a qualified supplier within the customer’s internal purchasing system, making future cooperation more efficient.
