Accepted Answer

MDF has very high requirements for surface quality, especially when surface decoration is applied, where a flat and fine surface is essential. A rough surface or sanding marks are usually related to improper control of the sanding process. JINDIWOOD uses a fine sanding process (180–240 grit sanding belts), ensuring surface roughness Ra ≤ 3.2 μm and thickness tolerance within ± 0.15 mm.

Question 14

How is the screw holding strength of MDF?

Accepted Answer

MDF has an internal bond strength ≥ 0.55 MPa, with good screw holding. Face screw holding can reach 700–1000 N. However, edge screw holding is relatively weaker. It is recommended to install hardware on the panel face as much as possible. If edge installation is required, pre-inserted nuts or additional connectors are recommended for reinforcement.

Question 15

Can MDF be used for extra-high cabinet doors?

Accepted Answer

MDF can be used for cabinet doors, but extra-high doors over 1.9 m have a deformation risk. Recommendations: ① choose high-density MDF (≥ 800 kg/m³); ② increase door thickness (≥ 22 mm); ③ install a straightener on the back of the door; ④ choose a moisture-resistant product and ensure proper edge sealing.

Question 16

What is the warranty policy for JINDIWOOD MDF?

Accepted Answer

JINDIWOOD MDF provides a 12-month warranty from the date of arrival. For quality problems such as insufficient internal bond strength, severe warping deformation, or large-area surface defects, we offer full compensation and cover the replacement shipping cost.

Question 17

What is the difference between MDF (Medium Density Fiberboard) and particle board?

Accepted Answer

MDF is made from wood fibers, which are fine and uniform, offering excellent surface flatness and suitability for decorative finishing and fine carving. Particle board is made from wood chips with a granular internal structure, providing good screw holding and better cost-effectiveness. MDF is ideal for decorative panel substrates, door profiles, and carved parts; particle board is suitable for cabinet bodies, shelves, and other structural components.

Question 18

What eco-friendly grades are available for MDF? How to identify them?

Accepted Answer

JINDIWOOD MDF offers three eco-friendly grades: E1 (≤ 0.050 mg/m³), E0 (≤ 0.025 mg/m³), and ENF (≤ 0.015 mg/m³). When purchasing, first check whether the product label information is complete, and confirm the product type and formaldehyde emission grade marking. It is recommended to choose a manufacturer with a good brand reputation and avoid products without labels or with a strong irritating odor.

Question 19

How is the moisture resistance of MDF? Can it be used in kitchens or bathrooms?

Accepted Answer

Standard MDF has average moisture resistance, with a 24-hour thickness swelling rate ≤ 15%. For humid environments such as kitchens and bathrooms, it is recommended to choose moisture-resistant MDF (24-hour thickness swelling ≤ 10%) with strict edge sealing. Unsealed MDF edges will swell severely after water contact, so it is not recommended for long-term water exposure or outdoor use.

Question 20

How does MDF perform in CNC carving and milling?

Accepted Answer

MDF is homogeneous, dense, and isotropic, making it the best material among all wood-based panels for CNC carving and milling. It can be CNC engraved, milled, grooved, and profiled, suitable for door profiles, Roman columns, decorative moldings, crafts, etc. The machined surface is smooth and requires no secondary repair.

Question 21

What thickness and sizes are available for MDF?

Accepted Answer

JINDIWOOD MDF thickness ranges from 2 mm to 30 mm, with common thicknesses including 2.5, 3, 4, 5, 6, 8, 9, 12, 15, 18, 22, and 25 mm. Standard size is 1220 × 2440 mm. Custom sizes such as 1220 × 2810 mm, 1220 × 3035 mm, and 1220 × 3660 mm are also available. Thin board density ≥ 830 kg/m³, thick board density ≥ 750 kg/m³, higher than national standard requirements.

Question 22

What should I do if the formwork blisters or partially delaminates?

Accepted Answer

Blistering and partial delamination are usually related to the following factors: excessive moisture content or uneven drying of veneers, excessive glue spread, too fast pressure release, insufficient pressing time, etc. If such problems occur, stop using the product immediately and contact JINDIWOOD after-sales service. Once confirmed as a quality issue, it will be handled under the “Full After-Sales Guarantee” policy.

Question 23

What causes film delamination or peeling on formwork?

Accepted Answer

Film delamination is usually related to the following factors: low hot-pressing temperature leading to insufficient film paper adhesion; poor base paper quality or uneven resin impregnation; failure to press into one integrated board during hot pressing; poor impregnation quality of the film paper. JINDIWOOD minimizes such problems through strict hot-pressing process control and the selection of high-quality base paper.

Question 24

What causes insufficient strength of formwork?

Accepted Answer

Insufficient formwork strength is usually related to low adhesive quality or improper control of hot-pressing conditions (temperature not high enough, pressure too low, time too short). JINDIWOOD formwork has a modulus of rupture ≥50 MPa (parallel to grain) and a modulus of elasticity ≥7500 MPa, far exceeding national standard requirements, ensuring construction safety.

Question 25

How should formwork be stored and maintained?

Accepted Answer

Proper storage and maintenance of formwork can significantly extend its service life: ① Clean concrete residue from the panel surface promptly after use to avoid scratching the film with hard objects; ② Store horizontally with wood blocks underneath to keep it flat; ③ Avoid direct sunlight and rain, and maintain ventilation; ④ Long-term storage areas should have rain and moisture protection measures; ⑤ Check formwork condition regularly and replace it promptly when film damage is found.

Question 26

What is JINDIWOOD’s warranty policy for formwork?

Accepted Answer

JINDIWOOD formwork comes with a 12-month warranty from the date the goods arrive. For quality issues such as insufficient bonding strength, severe blistering or delamination, or reuse times far below the promised standard, we provide full compensation and cover replacement shipping costs. Damage caused by improper construction operations or improper storage is not covered by the warranty.

Question 27

What is film faced formwork plywood? What is the difference from ordinary formwork?

Accepted Answer

Film faced formwork plywood is an engineered formwork panel made of a high-quality plywood substrate, covered with a phenolic resin-impregnated film and bonded under high temperature and high pressure. Differences from ordinary formwork: ① The surface film layer is waterproof and wear-resistant, allowing 20–30 reuses, compared with only 3–5 for ordinary formwork; ② The poured concrete surface is smooth as a mirror, achieving a fair-faced concrete effect; ③ Resistant to acid, alkali, and weather, suitable for various construction environments.

Question 28

What factors affect the reuse times of formwork plywood?

Accepted Answer

The reuse times of formwork plywood are affected by multiple factors: ① Film quality — resin impregnation amount and curing degree determine wear resistance and alkali resistance; ② Core hardness — hardwood core (eucalyptus/birch) has better compression resistance than softwood core (poplar); ③ Construction operations — proper stripping and timely cleaning of residual mortar can greatly extend service life; ④ Storage conditions — horizontal storage, rain and moisture protection, avoiding prolonged sun exposure; ⑤ Release agent use — reasonable use protects the film layer.

Question 29

How to choose the thickness and grade of formwork plywood?

Accepted Answer

The thickness selection of formwork plywood should comprehensively consider concrete lateral pressure and support spacing. Common thicknesses are 12–30 mm, with 18 mm being the mainstream in the market. Grade selection recommendations: low-rise residential (≤6 floors): choose 15 mm glued/film-faced panel; mid-to-high-rise (7–18 floors): choose 18 mm high-quality film-faced panel; super high-rise (≥30 floors): choose 18–20 mm high-strength film-faced panel (hardwood core); fair-faced concrete: choose premium film-faced panel. The higher the reuse requirement, the higher the grade should be selected.

Question 30

What is the difference between the surface colors of formwork plywood?

Accepted Answer

The film colors of formwork plywood (black, brown, red) mainly differ in film paper material and brand identification; the color itself does not affect physical performance. Different manufacturers use different colors for brand differentiation. When purchasing, focus on film paper quality rather than color.
