Product Description
4 Cavities PVC Sink J Bend P Trap Mold
This is a 4-cavity J Bend P Trap mold. There are 6 oil cylinders on the upper and lower sides of the mold to control the
core to be pulled out of the product. The most important of them are the two sets of oil cylinders on the central axis
that control the rotation of the core of the two arc segments. We designed a Crank-Slider Mechanism. The linear
motion of the hydraulic cylinder is converted into the rotation of thecrank. In this way, the arc core can be separated
from the product.
PVC Sink J Bend P Trap Mold Details
J Bend P Trap Mold Structure
The core of this j bend p trap mold is the core pulling action of the j bend arc segment. Its core is composed of a 1-to-
2 Crank-Slider Mechanism. This special four-bar linkage mechanism drives the mold core to rotate through the
extension and retraction of the hydraulic cylinder.
We designed a two-step separation for the core part of this J Bend P Trap mold. Because rotating the core 90
degrees is not enough to completely separate from the product. If the angle is increased, the core and the product will
interfere with each other. Therefore, we designed two fixed points on the crank part. When the core rotates 90
degrees, the first fixed point is released. The crank rotates around the second fixed point, one end of the core will rise,
and then separate from the product.
J Bend P Trap Mold Dynamic Simulation
As shown in the video. This J Bend P Trap Mold Crank-Slider Mechanism has 3 steps in total.
Step 1: The hydraulic cylinder first pulls the slider up a certain distance and pulls out the slider of the J Bend port;
Step 2: The rising slider is locked, driving the pull rod to rise. The pull rod pushes the slider groups on both sides to
rotate 90 degrees;
Step 3: The first fixed point is released, and the pull rod continues to push the crank to rotate. The product is
completely separated from the core.
4-Cavity PVC P Trap Molds: Efficiency Meets Precision
A 4-cavity P Trap mold is designed to maximize production efficiency by molding four units per cycle. This multi-cavity
approach manufacturing costs and cycle times, making it ideal for large-scale orders. Here's what sets high-
performance P Trap molds apart:
1. Advanced Mold Design
Flow Analysis: Optimized runner and gate systems ensure even material distribution across all cavities, minimizing
defects like air pockets or warping.
Cooling Channels: Strategically placed cooling lines reduce cycle times by accelerating solidification of PVC.
Durable Steel Construction: Heat-treated tool steels (e.g., H13 or S136) enhance mold longevity, even under high-
pressure injection molding conditions.
2. Consistency & Quality Control
4-cavity molds ensure uniform wall thickness and dimensional accuracy across all units, critical for leak-proof
performance. Automated ejection systems further streamline production while protecting delicate J Bend structures.
3. Cost-Effective Scalability
By quadrupling output per cycle, manufacturers achieve faster ROl while maintaining tight tolerances (#0.02mm). This
scalability is vital for meeting global demand for PVC sink traps.
Sink Plumbing Knowledge: Why P Trap Molds Matter in Sink Plumbing Systems
The sink trap (commonly a J Bend P Trap) is a U-shaped pipe under sinks that retains a small amount of water to
block toxic gases and odors. Made from corrosion-resistant PVC, these traps are lightweight, affordable, and easy to
install.
Key features of an effective J Bend P Trap include:
Smooth internal walls to prevent clogs.
Accurate bend angles for optimal water sealing.
Durable PVC material resistant to chemicals and temperature fluctuations.
Q1:What is your business scope?
A1: Our factory provides CNC plastic prototype, Plastic injection mould, moulding production, logo print and color painting.
Q2:Can you help to share an idea for a new product?
A2: Yes. We are always happy to cooperate with potential customers to evaluate the technical feasibility. Like, choose the right material, optimized the design, DFM report, and building cost etc.
Q3:Can you make double color injection mold or over-molding mould?
A3: Yes, we can. Have made lots of double color molds for brand earphones.
Q4:Which country do you frequently work with?
A4: Our customer groups mainly from USA, Canada, Mexico, Australia, Japan, Singapore, India, Israel etc.
Q5:How to have my components quoted?
A5: Please share us your drawings with 3D format (.STEP or .IGES files) and detailed BOM sheet. We are pleased to sign the NDA with your company.
A7: It is about 4 to 7 days for qty less than 5sets, and 7 to 12 days for qty above 10sets. Before painting process, we will polish and test part assembly, and then share video for confirmation.
