Product Guide
Application Scenarios+
Cooling circuit plugs are used in injection mold interior cooling channels to maintain a stable, leak-tight coolant pathway. This variant is suited for factory-built mold bases where screw plugs must seal reliably against pressure fluctuations and thermal cycling.
Common scenarios include:
- Automotive connector and latch molds: plug the end of drilled cooling circuits to prevent coolant leakage that can cause uneven thermal conditioning and dimensional drift.
- Packaging and consumer appliance tooling: use in molds with compact cooling layouts where the hex-socket flange supports secure installation and helps keep the O-ring compressed for long service life.
- Industrial/medical housing molds: protect coolant integrity to reduce contamination risk that can affect process stability and repeatability.
The screw diameter range M = 8–27 mm helps match typical screw-plug interface sizes, while the O-ring sealing approach supports sealed operation during repeated heating/cooling cycles.
Material & Process Details+
The provided data specifies the MSWM cooling circuit plug configuration and screw diameter range (M = 8–27 mm), but it does not include the steel grade, hardness (HRC), or heat-treatment state. Therefore, material-property claims (e.g., H13 vs. SKD61 equivalency) cannot be stated from the current specifications.
For engineers specifying durability, the key functional requirements for cooling-circuit plugs are:
- Wear resistance at the sealing interface to maintain O-ring compression over time
- Toughness to resist damage during repeated installation/removal
- Corrosion resistance to protect the plug body and sealing seat against coolant exposure
If you need a specific performance target (hardness HRC, nitriding, or quench-and-temper), share the preferred material or operating conditions and we can align the grade and treatment to your coolant and pressure profile.
Sizing & Selection Guide+
Selection starts by matching the plug’s screw diameter (M) to your mold’s threaded screw-plug interface. For this series, the variable M (Screw diameter) is 8 ~ 27 mm, so choose the unit whose M size corresponds to the threaded opening or screw plug diameter in your cooling circuit end cap design.
- Step 1: Measure the thread interface in the mold block (or the screw plug spec). Confirm the nominal diameter in the 8–27 mm range.
- Step 2: Verify sealing seat alignment: the O-ring requires proper face/seat geometry so that compression remains consistent under clamp-off and thermal cycling.
- Step 3: Consider installation fit: use the correct thread class for your mold standard to avoid either over-tightening (excess O-ring squeeze) or under-tightening (risk of leakage).
Only the M range is provided here; if length, flange dimensions, or tolerance class are required for your cavity/core drawings, consult the full dimensional table for the exact variant you intend to use.
Frequently Asked Questions
How do I select the correct MSWM cooling circuit plug size for my mold’s threaded port?+
This series is specified by the screw diameter M, with a range of M = 8 ~ 27 mm. Select the plug variant whose M matches the nominal diameter of the threaded cooling-circuit port or screw plug interface in your mold block.
After sizing, verify that the sealing seat geometry supports proper O-ring compression to prevent leakage under operating pressure.
What features of the MSWM plug help prevent coolant leaks and contamination?+
The MSWM configuration is designed for a sealed fit using an O-ring, aiming to prevent coolant leakage and contamination. The hex socket flange provides controlled installation and stable positioning, which helps maintain consistent compression at the sealing interface.
This is particularly important when coolant flow and mold temperature fluctuate during production cycles.
Can this cooling circuit plug be used with compact cooling layouts where access is limited?+
Yes, the hex socket flange is intended to support practical installation using a hex-socket tool, which can be beneficial in tight mold spaces. It helps keep the plug properly seated while securing the assembly to the cooling circuit end.
Choose the correct M = 8–27 mm variant to match the available thread diameter.
Do you provide material grade, HRC hardness, or heat-treatment details for the MSWM plug?+
The current specifications provided here list the screw diameter range (M = 8 ~ 27 mm) but do not include a steel grade, hardness (HRC), or heat-treatment condition. As a result, equivalencies and treatment states (e.g., quench-and-temper, nitriding) cannot be confirmed from the supplied data.
If you need a specific hardness or treatment for your coolant conditions, share your target requirements and we can help align the correct material/process specification.
