Handheld Instrument Dual Color Injection Plastic Enclosures Parts
This series of dual-color injection molded instrument enclosures is specifically designed and manufactured for high-precision handheld testing equipment (such as Leeb hardness testers, ultrasonic thickness gauges, multi-functional multimeters, and various portable sensing instruments).
We utilize industry-leading Two-Shot / Double Injection molding technology to perfectly fuse the ultra-high rigidity of rigid substrates (such as PC/ABS or reinforced nylon) with the flexible tactile feel of soft outer layers (such as TPE/TPU) on a single precision dual-color injection molding machine. The resulting products not only feature sharp, aesthetically pleasing lines but also offer excellent structural dimensional stability and outstanding industrial-grade drop cushioning protection.

Product Advantages
Molecular-Level Bonding, Zero Delamination
Unlike traditional manual rubber sleeving or conventional secondary adhesive bonding, this product achieves molecular bonding under a molten state inside the dual-color mold. Even during long-term use in harsh industrial environments with extreme cold, high temperatures, or high humidity, the overmolded edges will never warp, blister, peel off, or allow water ingress.
Ultimate Shock Resistance & Protection
Thick engineering-grade soft rubber wraps around the enclosure's perimeter, grip areas, and high-wear corners. This unique design effectively absorbs up to 80% of drop impact energy, providing comprehensive protection for expensive internal PCB mainboards and LCD screens.
Excellent Ergonomic Feel
The soft rubber surface is designed with a micron-level fine anti-slip leather texture, complemented by scientifically laid out anti-slip stripes on the sides. This ensures that technicians can maintain a secure grip in industrial field environments—even with sweaty, oily hands, or while wearing gloves—preventing accidental drops.
Striking Multi-Color Aesthetics & Brand Recognition
We offer various high-contrast dual-color combinations such as red/black, yellow/black, and blue/black. The color boundary lines are crisp and sharp, with zero flashing or color mixing, significantly enhancing your instrument's product tier and brand recognition.

Frequently Asked Questions
1
Q: What is the difference between dual-color injection molding and ordinary overmolding?
A: Dual-color injection molding is completed on a specialized dual-color injection molding machine equipped with two barrel injection systems. The mold automatically rotates and switches inside the machine. Immediately after the rigid plastic is injected and before its surface has completely cooled, the soft rubber is injected. The two materials bond in a semi-molten state, resulting in tightly intertwined molecular chains. In contrast, ordinary overmolding usually requires workers to manually remove the rigid plastic parts after they have cooled down, and then manually place them into another standard injection molding machine for secondary injection. This leads to a longer production cycle, and due to heat loss, the bonding strength between the two materials is far inferior to that of dual-color injection molding.

Q: Can we provide our own designed PCB, and can you help us fully customize the enclosure?
A: Absolutely! We provide a one-stop custom service. The customization workflow is as follows:Your company provides the 3D drawings of the PCB (in STP/STEP format) →Our engineering team performs the 3D structural design of the enclosure and dual-color mold flow analysis →Both parties confirm the drawings →Precision dual-color mold manufacturing →Mold trial and sampling →Testing and confirmation by your company →Large-scale mass production.

Q: How do you guarantee that the enclosure can meet IP65 or IP67 waterproof and dustproof ratings?
A: We achieve this primarily through two key approaches:
Structural Design Advantage:We take full advantage of dual-color injection molding to directly co-mold a soft rubber sealing ring (TPE) at the joint/groove interface of the front or rear housing. This completely replaces traditional manual silicone O-ring placement.
Interlocking Mechanics:The interlocking joint where the front and rear housings meet is designed with a labyrinth-style multi-channel waterproof groove. Combined with high-density screw fastening, it ensures an exceptional airtight and watertight seal.
