HTX Standard SKD61 Nitrided Ejector Pins Supplied to a Mexican Mold Component Distributor
Hero Summary
A mold components distributor from Mexico was looking for a certified Chinese injection mold parts factory for standard ejector pins. As this was the customer’s first purchase of mold components from China, product quality, material certification, and delivery reliability were the primary concerns.
HTX supplied 186 pcs of SKD61 nitrided ejector pins with material certificates and hardness reports, and arranged shipment within three working days, helping the customer establish a reliable sourcing channel for future orders.

Customer Background
The customer’s previous business model involved sourcing from other local suppliers or European brands and then reselling to local mold manufacturers.
Before this order, they had only purchased equipment such as injection molding machines from China, and those transactions had gone quite smoothly. However, the situation was different for mold components—especially ejector pins. If a failure occurred during production, the mold had to be stopped, disrupting the customer’s production line.
The Challenge: Finding a Reliable Chinese Supplier
When exploring Chinese suppliers for standard ejector pins, their main concerns included:
- Was the material genuine?
- Can hardness certificates be provided?
- Can the delivery meet their schedule?
- Can the Chinese supplier provide stable quality for future orders?
Technical Insight:
Why Choose SKD61 Vacuum Nitriding?
The vacuum nitriding process diffuses nitrogen atoms into the surface of the ejector pin, forming a hard, wear-resistant nitrided layer without causing brittleness or dimensional distortion. In mass production, nitrided ejector pins are less prone to burr formation and perform particularly well under conditions involving high-temperature resins or insufficient lubrication. Under high-temperature injection molding environments, the nitrided layer forms a hard and thermally stable barrier, effectively extending the service life.
For distributors who need to meet the demands of various mold operating conditions, a single product can cover multiple application scenarios, and having fewer stock types reduces customer complaints.
This is the primary reason HTX has chosen vacuum-nitrided ejector pins as its standard stock: the same material, but with a longer service life.
Storage & Lead Time: Why 3 Days?
SKD61 nitrided ejector pins in standard diameters and lengths are not made to order; we maintain a long-term stock of ready-to-ship items in our store. This allows HTX to respond faster than suppliers who require production before shipment.
Once an order is confirmed, there is no need to wait for raw materials or the nitriding process. Warehouse staff immediately arrange for picking, pre-shipment inspection, export-standard packaging, and shipping arrangements. The entire process—from the customer placing the order to the logistics company picking up the shipment—is completed within 3 days.
Manufacturing Process and Quality Inspection:
Since we maintain a large inventory of SKD61 ejector pins in commonly used diameters and lengths, this batch of ejector pins is one of our strengths.
Standard SKD61 steel already possesses good thermal stability, but after undergoing vacuum nitriding with strictly controlled nitriding times and temperatures, it not only retains its original internal toughness but also achieves a surface hardness of 65–68 HRC. This ensures excellent performance during friction with the ejector plate and helps reduce wear and improve reliability during repeated ejection cycles.
Each batch undergoes dimensional inspection, surface finish verification, and hardness testing. Material certificates and hardness test reports are provided to the customer along with the shipment.
Fast Shipping Options for Urgent Orders
This customer asked us for shipping options. After checking with the freight forwarder, we offered the customer two shipping options: DHL and FedEx. The shipping cost for DHL to the customer’s address was $60 higher than that of FedEx, but the delivery time was 5–6 days faster. The customer replied, “I will use DHL this time due to the time I have committed.” At last, we shipped the 186 pcs of nitriding ejector pins with DHL.
Project Results
| Before | After |
| No established supplier in China | Reliable sourcing partner established |
| Uncertainty about material quality | Material and hardness certificates provided |
| Concern about delivery time | Order shipped within 3 working days |
| Limited sourcing options | Expanded product range available for future orders |
Customer Feedback
After one week, he got the package, and he told us: “Hola, gracias. Los recibí ayer, todo bien.” “Hello, thank you. I received them yesterday. Everything is good.” “Enviaré el listado en un rato”,”I will send the list in a while”
The customer also expressed interest in purchasing a wider range of ejector pins and provided additional requirements on the second day.
Engineering Insights
What did we learn from this project?
- Material certification is often as important as product quality for first-time overseas buyers.
- Maintaining an inventory of standard ejector pins significantly shortens delivery time.
- Providing multiple shipping options helps overseas distributors balance delivery time and logistics cost.
- For customers purchasing from a new overseas supplier, quick responses and transparent communication help reduce uncertainty during the sourcing process.
