Less pressure on parts.
Lower molding pressure can help protect sensitive electronic parts, solder joints and connectors during molding.
Cable · Wire · Connector protection
Protect your cables.
Support every
connection.
Darbond low-pressure molding (LPM) materials cover and protect cable joints, connectors and electronic parts. Choose a softer or firmer material to suit your product.
Melt → Inject → Cool
One material. Melt it, mold it, then let it cool. No A/B mixing or chemical curing.
Why low-pressure molding?
Protect the connection.
Simplify the process.
The material, mold and machine work together to protect your product.
Protection in one step.
One molded cover can protect the joint, provide insulation and support the cable where it bends. This may reduce the number of separate protective parts.
Sets as it cools.
Use one hot-melt material, with no mixing or chemical curing. Handle the molded part once it has cooled enough.
Where it fits
Protection for cables,
connectors and joints.
Tell us what the part does, how it moves and where it is used. We can then discuss the material and mold design.
Cables & wire joints
Support the cable where it leaves the connector. Check how well the material bonds and how the part handles pulling and bending.
Consider: HM107 / HM108 for flexible profiles
Connector assemblies
Cover solder joints and small circuit boards inside connectors. Check bonding to the cable jacket and housing, and test electrical performance.
Consider: HM101 / HM109 for bonding needs
Automotive connections
Check changes in temperature, vibration, fluid contact and sunlight. Choose a material that passes the tests your product needs.
Consider: HM103 for vehicle and sunlight exposure
Photos show application examples. Test the suggested materials on your own parts before final selection.
Choose the hardness
Softer for movement.
Firmer for shape.
Hardness is only one factor. Also check bonding, part shape, temperature and the forces on the part.
Shore A / SOFTER MATERIALS
Flexible cable ends & covers
A softer molded cover may suit cables that move or bend. Test repeated bending, pulling and bonding on the actual part.
HM108 · 78A / HM104 · 86A
HM103 / HM107 · 88A
HM103 / HM107 · 88A
Shore D / FIRMER MATERIALS
Covers that hold their shape
A firmer material may suit covers that need to hold their shape. Check impact resistance, fit and operating temperature.
HM101CL · 40D / HM101 · 41D
HM105 · 45D / HM106CL · 50D
HM105 · 45D / HM106CL · 50D
Shore A and Shore D are different hardness scales. Do not compare their numbers directly. Hardness alone does not tell you how stiff a part will be or what temperature it can withstand.

These are typical values. Viscosity is measured at the temperature shown, so values at different temperatures cannot be compared directly. Softening point is not the maximum operating temperature. The listed storage reference for the HM101–HM108 materials shown here is 24 months at 8–28°C. Check the current TDS and packaging instructions.
Common cable problems
Too many steps.
Too much rework?
If these problems sound familiar, LPM may offer a simpler way to protect and position your cables.
Too much wrapping and assembly?
Tape, sleeves and separate covers can add manual work.
How LPM can helpCombine protection and shaping in one molding step, where suitable.
Cables hard to keep in position?
Uneven cable spacing can make assembly more difficult.
How LPM can helpA molded wire retainer helps keep cables organized.
Joints need more support?
Pulling and repeated bending can put stress on cable connections.
How LPM can helpAdd molded support around the joint or cable exit. Test grip and bending on your part.
Finished parts look different?
Hand-applied protection can vary from operator to operator.
How LPM can helpA defined mold helps produce a consistent shape.
Waiting for potting to cure?
Mixing and curing can add steps and waiting time.
How LPM can helpHot-melt LPM sets by cooling, without a chemical curing step.
Material suitability, cable grip and protection depend on the design and require testing.

Small parts. Useful protection.
Cable connection protection
Before and after molding: cover the board and wire joints in one compact part.
Wire retainer
A small molded retainer helps keep two cables positioned together.

From material to molded part
Four steps to a suitable material.
Share your part.
Send a drawing or describe your sample. Tell us the cable-jacket material, connector material and where the part will be used.
Set the priorities.
Tell us the bonding, hardness, flexibility, electrical and temperature requirements.
Plan the mold.
Plan how the material enters and fills the mold, how air escapes and how the part is held in place.
Test actual parts.
Agree on pass/fail limits. Test molded samples under the conditions your product will face.

Common questions
Before you select a grade.
Does a harder grade always give better protection?
No. A harder cover may hold its shape better. A cable that bends may need a softer material. Also check bonding, part shape, forces and operating conditions.
Can LPM replace heat-shrink tubing or potting?
LPM may work where one molded cover can provide both protection and support. Check production quantity, mold cost, material bonding and required tests. Compare the processes using actual parts.
Is the softening point the operating-temperature limit?
No. Softening point comes from a specific material test. Check the TDS for operating limits, then test your part at the temperatures and loads it will face.
Are waterproofing and flame performance guaranteed?
Results depend on the material, surfaces, part design and molding process. Check the material documents for the flame rating you need. Test sealing on the finished part.
