Production Process Line Steps & Quality Controls
Rigorous sequence executed inside our 20,000 sq ft Traverse City plant.
Substrate Pretreatment
Parts undergo chemical de-greasing, grit-blasting, and application of a thermal-bonding primer to prevent future rust-creep if the vinyl is mechanically gouged.
Precision Preheating
Components are suspended and baked in automated convective ovens at 375°F to 425°F. The exact dwell time and thermal mass determine the coating's final thickness.
Controlled Immersion
Parts are smoothly lowered into custom formulation dipping tanks under steady speed curves to guarantee uniform gelation without run marks or air pocket entrapping.
Thermal Curing & Fusing
The gelled vinyl layer is baked again at 380°F to cure the vinyl, ensuring complete polymerization and maximum abrasion protection.
Water Quench & Inspection
Quick cooling preserves the desired surface texture (gloss, satin, or matte) and locks in physical elastomeric bounds. 100% spark testing is done for high-voltage applications.
Formulated Materials Options
- Standard B2B high-gloss vinyl (tough, sleek, easy-to-clean)
- Premium textured matte formulation (high-friction operator grip)
- Dielectric electrical formulation (high-isolation, UL recognized)
- FDA-grade non-toxic formulation (sterilizable, compliant)
- UV-resistant coating (weather & UV protection)
- Chemical-resistant formulation (oil & abrasion resistant)
Target Standard Applications
- Automotive brackets, structural stampings, and anti-rattle body clips
- Hand tools, heavy wrenches, metal cutters, pliers, and hydraulic handles
- Electrical bus bars, current terminals, transformer covers, and distribution brackets
- Playground chains, marine hooks, and material handling steel baskets
Standard Engineering FAQs
Q: What is the typical thickness achievable in a single dip?
A: We can reliably deposit anywhere from 0.005 inches up to 0.250 inches of plastisol in a single heat cycle. Multi-dipping is also an Available standard for ultra-dense shock protection.
Q: Do you offer a permanent bond that won't slide off?
Q: What is the maximum part size PDM can coat?
A: Our standard dip tanks accommodate parts up to 24″ × 36″ × 8″. Larger parts can be accommodated with custom tooling send us your part drawings.
Q: Can PDM match specific Pantone or RAL colors?
A: Yes. Our in-house chemists can formulate plastisol to match most Pantone and RAL color references. Custom color matches require a small batch minimum.
Q: Does plastisol coating meet military specifications?
A: Yes. We have experience coating to multiple military specifications including MIL-PRF and MIL-DTL standards. Contact us with your specific spec requirements.
Q: What is the typical lead time for plastisol dip coating?
A: Standard production runs ship in 2-3 weeks. Expedited service is available. We routinely accommodate rush orders for automotive OEMs.
Q: What industries use plastisol dip coating services?
A: Plastisol dip coating is used in automotive, medical, industrial, and electrical applications. It provides durable protection, improved grip, insulation, and corrosion resistance.
Q: Why choose PDM Industries for plastisol dip coating?
A: PDM Industries has over 50 years of experience delivering reliable plastisol dip coating services with consistent quality, precision, and custom solutions for OEMs.
